RESUMEN
Objective: This study aimed to assess the association of body mass index (BMI) with anal high-risk human papillomavirus (HR-HPV) and biopsy-confirmed histologic anal high-grade squamous intraepithelial lesions (HSIL) among a clinic-based sample of Hispanics in Puerto Rico. Methods: This cross-sectional study evaluated medical records of adults who received services at the Anal Neoplasia Clinic of the University of Puerto Rico Comprehensive Cancer Center between October 2014 and December 2022. The study included 543 records with complete clinical information regarding anal HR-HPV and anal HSIL status. Chi-square and logistic regression analyses were performed. Results: Mean age of participants was 44.10 ± 13.24 years, 65.2% were men, 71.7% were HIV-infected, 74.4% had anal HR-HPV infection, and 37.9% had biopsy-confirmed HSIL. Regarding BMI, 2.4% were underweight, 31.9% normal weight, and 39.0 % overweight; while 17.3 % had class I, 5.2% class II, and 4.2% class III obesity. No significant association was observed between BMI and anal HR-HPV infection in adjusted analyses. Lower odds of anal HSIL were observed among overweight individuals (OR: 0.63, 95% CI: 0.41 - 0.99) and those with class II/III obesity (OR: 0.48, 95% CI: 0.22 - 1.01) compared to adults with underweight/normal BMI, after adjusting for potential confounders. No significant association was observed for class I obesity. Conclusion: BMI was not associated with anal HR-HPV infection. Overweight and obese individuals had lower odds of having anal HSIL than adults with underweight/normal BMI. This finding could suggest underdiagnosis of HSIL among overweight/obese individuals, or reduced risk in this group.
RESUMEN
Background: Limited research exists regarding the association between smoking and anal warts. In this study, we evaluated this association among a clinic-based Hispanic population in Puerto Rico. Methods: Cross-sectional study among eligible patients seen at the Anal Neoplasia Clinic of the University of Puerto Rico Comprehensive Cancer Center (2016-2023) (n = 920). Sociodemographic and clinical variables were collected from medical records. Patients underwent a high-resolution anoscopy (HRA) during the clinical visit; physicians assessed anal condylomas on HRA. Poisson regression models with robust standard errors were used to evaluate the association between smoking and anal warts. Demographic and clinical factors were also assessed. Results: The mean age of participants was 45.8 ± 13.1 years, 66.4 % were men, and 21.6 % were current smokers. While 10.8 % self-reported a history of anogenital condylomas, 18.9 % had anal condylomas on clinical evaluation. A higher prevalence of anal condylomas was observed among current smokers (PR = 1.28, 95 % CI: 0.94-1.75) in comparison to non-smokers in adjusted analysis, but this was not statistically significant. However, a higher prevalence of anal condylomas was observed among younger individuals (PR = 0.96, 95 % CI: 0.96-0.98) and individuals with anal high-grade squamous intraepithelial lesions (HSIL) as compared to those with benign histology (PR = 1.74. 95 % CI: 1.09-2.77). Conclusions: Although current smoking seemed to be positively associated with anal condylomas in this high-risk Hispanic population, this finding was not statistically significant as the power to detect an association was limited. However, younger age and HSIL diagnosis were associated with a higher prevalence of anal condylomas.
RESUMEN
BACKGROUND: Given the disproportionately elevated anal cancer risk in high-risk populations, it is important to assess the performance of commonly used anal cancer screening tools to improve the effectiveness of detection and treatment methods. This study evaluates 1) the concordance between anal cytology and histology results and 2) the performance of cytology and high-risk human papillomavirus (HR-HPV) genotyping as screening tools for detecting histologically confirmed anal high-grade squamous intraepithelial lesions (HSIL). METHODS: Data from the Anal Neoplasia Clinic in Puerto Rico (2014-2021; n = 466) was used. The clinical performance of anal cytology and HR-HPV genotyping to detect HSIL was compared to the gold standard: high-resolution anoscopy-guided biopsy. Sensitivity, specificity, positive predictive value, negative predictive value, and κ coefficients were calculated. RESULTS: A total of 66.95% of the patients were men, 74.0% were people living with HIV, 76.2% had anal HR-HPV infection, and 40.34% had histologically confirmed anal HSIL. The weighted κ statistic between the tests (cytology and histology) was 0.25 (p < .001). The sensitivity and specificity of cytology alone to detect anal HSIL were 84.3% (95% confidence interval [CI], 78.3%-89.1%) and 36.0% (95% CI, 30.3%-42.0%), respectively. Anal HR-HPV genotyping had higher sensitivity (92.2%; 95% CI, 87.4%-95.6%) and similar specificity (34.8%; 95% CI, 29.2%-40.7%) compared to cytology. The two tests combined (positive results following cytology or HR-HPV test) improved sensitivity to detect anal HSIL (97.9%; 95% CI, 94.8%-99.4%), but specificity was compromised (19.2%; 95% CI, 14.7%-24.4%). CONCLUSION: Although HR-HPV genotyping improved the detection of anal HSIL, HR-HPV testing had lower specificity than anal cytology alone.

Introduction: The COVID-19 pandemic pressured health care systems to remain alert and active in their vector-borne disease control and prevention programs, leading to changes in vector control strategies in urban areas affected by dengue, Zika and chikungunya. Objective: To describe the adaptations made to the vector control and surveillance program in Medellín during the COVID-19 health emergency. Materials and methods: Once the health emergency started, biosecurity protocols were developed. Entomological surveillance was strengthened from the institutional environment instead of homes. Data was collected in Medellín from 2018 to 2021 during the vector control and surveillance program activities, which included epidemiological and entomovirological surveillance, entomological index survey, ovitrap monitoring, community mobilization, search and elimination of mosquito breading sites, and chemical control. These actions were adapted and/or increased to promote self-care among communities in total and partial confinement, and to develop prevention and control measures. Results: Mosquito monitoring was increased by 40% using ovitraps, entomological virological surveillance showed an increase in 2020 of 34,4% compared to 2019 and virtual media was used to keep and improve contact with the community. Conclusion: The COVID-19 pandemic had a significant impact on arbovirus prevention and control programs. The city of Medellín quickly adapted its entomo-virological surveillance activities, control measures, and the contact with the community during the pandemic, which allow the Integrated Vector Management program to remain active in the city.

Background: Persons living with HIV (PLWH) are at high risk of developing anal high-grade squamous intraepithelial lesions (HSIL). We aimed to develop a prediction model for anal HSIL based on individual characteristics of PLWH. Methods: Cross-sectional study of PLWH aged ≥21 years who attended the Anal Neoplasia Clinic of the University of Puerto Rico Comprehensive Cancer Center from 2016 to 2022. The primary outcome was biopsy-confirmed anal HSIL. For each sex, relations between potential predictors and HSIL were examined using univariate (ULRM) and multivariable (MLRM) logistic regression models. Risk modelling was performed with MLRM and validated with bootstrapping techniques. The area under the ROC Curves (AUC) was estimated with 95% CI. Findings: HSIL was detected among 45.11% of patients, 68.48% were males, and 59.42% were ≥45 aged. Multivariable analysis showed that, in women, the only significant predictor for HSIL was having a previous abnormal anal cytology (p = 0.01). In men, significant predictors for HSIL were having a previous abnormal anal cytology (p < 0.001) and a history of infection with any gonorrhoea (p = 0.002). Other suggestive predictors for HSIL among women were obesity and smoking. No association between smoking and HSIL among men was observed (p < 0.05). The AUC estimated among women (0.732, 95% CI: 0.651-0.811) was higher than in men (0.689, 95% CI: 0.629-0.748). Interpretation: Our results support that the inclusion of individual characteristics into the prediction model will adequately predict the presence of HSIL in PLWH. Funding: This work was supported by the NCI (Grants #U54CA096297, #R25CA240120), the NIGMS (Grant #U54GM133807), and the NIMHD (Grant #U54MD007587).
RESUMEN
Kasabach-Merritt syndrome is a rare but life-threatening disease in which a rapidly growing vascular tumor induces localized intravascular coagulation, causing thrombocytopenia, microangiopathic hemolytic anemia, and consumption coagulopathy. It presents mainly in infants and young children. We present an adult with recurrent and severe lower gastrointestinal bleeding due to Kasabach-Merritt syndrome, treated successfully with sirolimus after multiple other failed interventions.
RESUMEN
INTRODUCTION: Current smoking is a risk factor for anal cancer. Yet, its association with anal human papillomavirus infection (HPV) and anal high-grade squamous intraepithelial lesions (HSIL) remains unclear. We assessed the association of smoking with 1) anal high-risk HPV (HR-HPV) infection and 2) anal HSIL. METHODS: Data from the baseline visit of patients from the Anal Neoplasia Clinic of the University of Puerto Rico Comprehensive Cancer Center (May 2015- June 2021) was analyzed. Patients were eligible if they had information on smoking status, complete high-resolution anoscopy (HRA) with biopsy, and HR-HPV testing (n = 427). Logistic regression models estimated the odds ratio (OR) with 95% confidence intervals (CIs) adjusting for covariates. RESULTS: Mean age was 44 ± 13 years, 69% were men, 74% were HIV-infected, and 25% reported being current smokers. 74% had anal HR-HPV infection. HSIL was diagnosed in 40% of patients. Current smokers had significantly higher odds (OR: 1.71, 95% CI: 1.04-2.82) of having HSIL compared to non-smokers after adjusting for age, sexual risk group, lifetime number of sexual partners, HIV status, and HR-HPV infection. Smoking was not associated with HR-HPV infection (OR: 1.56, 95% CI: 0.83-2.95) after adjusting for age, sexual risk group, lifetime number of sexual partners, and HIV status. CONCLUSIONS: Current smoking was associated with histologically confirmed HSIL but not with HR-HPV infection among this high-risk Hispanic population. Results highlight the need to explore targeted smoking cessation campaigns among populations at higher risk of developing HSIL, as an anal cancer prevention strategy.
RESUMEN
Radiotherapy treatment-induced intestinal injury and gut microbial perturbation/dysbiosis have been implicated in the pathobiology of cancer-related fatigue. The objective of this brief review was to explore the available evidence of the relationship between intestinal injury and self-reported fatigue, especially among cancer patients. The scientific evidence-including our own-linking gut mucosal barrier dysfunction and gut microbial perturbation/dysbiosis induced by cancer treatment with worsening of cancer related fatigue (perhaps through the gut-brain axis) is limited but promising. Emerging data suggest that lifestyle interventions and the administration of specific probiotics may favorably modulate the gut microbiota and potentially mediate beneficial effects leading to improvements in fatigue.

OBJECTIVE: The aim of the study was to evaluate the validity of anal cytology against high-resolution anoscopy in the detection of anal high-grade squamous intraepithelial lesions (HSILs) among women in a clinical setting in Puerto Rico, alone and in combination with high-risk human papillomavirus (HR-HPV) typing. MATERIALS AND METHODS: A cross-sectional study was done among 128 eligible women who attended the Anal Neoplasia Clinic of the University of Puerto Rico Comprehensive Center between 2014 and 2019. Kappa (κ) coefficient, sensitivity, specificity, positive predictive value, and negative predictive value were calculated using high-resolution anoscopy with biopsy as the criterion standard test. Poisson regression was used to estimate the adjusted prevalence ratio of anal HR-HPV infection. RESULTS: Overall, 71.1% of women were HIV infected and 78.9% had anal HR-HPV infection. Squamous intraepithelial lesions were detected with anal cytology and histology in 70.3% and 81.3% of women, respectively. The κ statistic between the tests (cytology and histology) was 0.32 (p < .05). Measured against the results from histology, the sensitivity of anal cytology alone to detect HSIL was 85.4% (95% CI = 72.2%-93.9%), whereas specificity was 38.8% (95% CI = 28.1%-50.3%). Although the sensitivity of the 2 tests combined (anal cytology and HR-HPV typing) to detect histologically confirmed HSIL increased (100.0%, 95% CI = 92.6%-100.0%), the specificity decreased (16.3%, 95% CI = 9.0%-26.2%). Meanwhile, women with HSIL had a higher prevalence of anal HR-HPV infection than those with no SIL/LSIL (prevalence ratio = 6.23, 95% CI = 1.50-25.83). CONCLUSIONS: Anal cytology in combination with HR-HPV typing for the screening of anal intraepithelial neoplasia improved the detection of HSIL in women.

OBJECTIVE: To estimate the magnitude of association between anal infection with high-risk human papilloma virus (HR-HPV) types and severity of biopsy-confirmed histopathological anal squamous intraepithelial lesions (SILs) among a clinic-based sample of HIV-infected adults in Puerto Rico. METHODS: This cross-sectional study analyzed data from medical records of adult patients who visited a specialized anal neoplasia clinic from June 2015 to December 2017 (n = 239); sociodemographics, behavioral risk factors, medical history, clinical data, and pathology reports were collected. The magnitude of association between anal HR-HPV and severity of anal SIL, adjusted for potential confounders, was assessed using a multinomial logistic model. RESULTS: A 78.7% of patients had anal HR-HPV infection, 43.9% had histopathological low-grade SIL (LSIL), and 37.7% had histopathological high-grade SIL (HSIL). The prevalence of anal HR-HPV infection was 63.6% among patients with no anal SIL, 70.5% for those with LSIL and 95.6% for those with HSIL. After adjusting for different predictors, patients with anal HR-HPV infection were more likely to have HSIL (odds ratio, 11.0; 95% confidence interval, 3.2-37.2) than those without anal HR-HPV infection, whereas no significant excess was observed for LSIL (odds ratio, 1.4; 95% confidence interval, 0.6-3.1). CONCLUSIONS: This study showed a strong association between anal HR-HPV infection and HSIL. Likewise, a high prevalence of anal HR-HPV infection and presence of anal SIL was observed among HIV-infected individuals. Our result highlights the importance of screening for anal HR-HPV infection and anal SIL and optimizing strategies for HPV vaccination in HIV-infected individuals.

OBJECTIVE: To examine the health related quality of life (HRQOL) experienced by 79 Puerto Rican adults during cancer treatments. METHODS: This study used a descriptive, cross-sectional design. Participants completed a demographics form and the Functional Assessment of Cancer Therapy-General QOL questionnaire (FACT-G). Descriptive statistics were generated. RESULTS: Participants were ages 28-78; most of the participants had breast (38.0%), prostate (14.0%) and cervical and ovarian cancers (10.1%) treated with chemotherapy (45.6%). The participants had a mean total score on the FACT-G of 75.2 (SD = 18.9). As a group, the functional well-being was the most affected (mean 17.2, SD 6.8), and the Social/Familial was the least affected (mean 20.7, SD 6.0). CONCLUSION: Cancer is the leading cause of death in the island of Puerto Rico. Female Puerto Rican cancer patients in this study sample had increased risk for experiencing worse: overall HRQOL, physical well-being and emotional well-being compared to males. Given that the Hispanic oncology population does not always report symptoms, risking under-assessment and under management, this suggests there may be a greater need for HRQOL surveillance for this population.

BACKGROUND: Marginal zone lymphomas (MZLs) are indolent disorders composed of 3 subtypes: extranodal marginal zone lymphoma (MALT), splenic marginal zone lymphoma (SMZL), and nodal marginal zone lymphoma (NMZL). Early-stage MALT is treated with radiotherapy or antibiotics, and advanced MALT and NMZL are managed with either watch and wait or chemotherapy. SMZLs are treated with splenectomy or rituximab. However, because these approaches have failed to cure patients with SMZL and NMZL, we have systematically used upfront chemotherapy for them, as well as for advanced MALT. We report the outcomes of this approach. PATIENTS AND METHODS: A total of 44 patients with MZL were identified from our database and divided into 2 groups. Group 1 (22 with early-stage MALT) patients received either radiotherapy (n = 17) or antibiotics with or without surgery (n = 5). Group 2 included 9 patients with advanced MALT, 9 with SMZL, and 4 with NMZL. Group 2 was treated with FND-R (fludarabine 25 mg/m2 on days 1 to 3, mitoxantrone 10 mg/m2 on day 1, dexamethasone 20 mg on days 1 to 5, and rituximab 375 mg/m2 on day 1; n = 14) or CHOP-R (cyclophosphamide 750 mg/m2 on day 1, doxorubicin 50 mg/m2 on day 1, vincristine 2 mg intravenous push on day 1, prednisone 100 mg/m2 orally on days 1 to 5, rituximab 375 mg/m2 on day 1; n = 8), followed by maintenance rituximab for 70%. RESULTS: All patients achieved complete remission, and only 2 patients in group 1 had developed a relapse at 70 and 75 months. Both relapses were stage I MALT that had initially been treated with radiotherapy. Both were salvaged with FND-R and remained free of disease at 27 and 39 months after the relapse. At 10 years, the failure-free survival for the 44 patients was 80% and the overall survival was 100%. None of the patients in group 2 developed a relapse. The long-term toxicities have been acceptable. CONCLUSIONS: The excellent responses using upfront chemotherapy for MZL suggests that this disorder is curable. Our results should be confirmed in a prospective trial.

Breast cancer is the leading cause of cancer death among Hispanic women. Certain dietary factors have been associated with the risk of breast cancer recurrence, but data in Hispanic survivors is scarce. OBJECTIVE: to examine dietary patterns and diet quality in two groups of Hispanic breast cancer survivors. METHODS: 23 Mexican-American (MA) and 22 Puerto Rican (PR) female breast cancer survivors completed a culturally adapted validated food frequency questionnaire. Intake was standardized per 1000 kcal and compared to US Dietary Guidelines and the DASH-style diet adherence score was calculated. RESULTS: Overweight/obese was 70 % in MA and 91 % in PR. PR consumed diets rich in fruit/100 % fruit juices and beans, while MA diets were high in vegetables, beans, and total grains. Both groups consumed high amounts of starchy vegetables, refined grains, animal protein and calories from solid fats and added sugars but low intakes of whole grains, dairy products and nuts and seeds. DASH scores were relatively low. CONCLUSION: MA and PR female breast cancer survivors have different dietary patterns but both groups had relatively low diet quality. These groups could benefit from culturally tailored interventions to improve diet quality, which could potentially reduce cancer recurrence. ClinicalTrials.gov Identifier NCT01504789.

Fungal infections represent a serious complication for immunosuppressed patients resulting in an increased morbidity and mortality. A non-concurrent prospective study was performed to evaluate the factors associated to invasive fungal infection (IFI) in patients with hematological malignancies admitted to the University Hospital in San Juan, Puerto Rico from January 1st, 2011 through June 15th, 2014. The medical records of 84 patients were evaluated. Fifty-nine patients with IFI and twenty-five without IFI. The majority were men between 35 to 55 years old. The main hematological diagnosis was acute myelogenous leukemia (AML) followed by acute lymphoblastic leukemia (ALL). Seventy-percent developed IFI. The most common fungi were C. albicans followed by non-albicans species, Fusarium and, Aspergillus species, respectively. About 63% of the patients with AML and 81% without AML had IFI. Those who received steroids were more likely to develop IFI. After adjusting for AML and age, the odds of IFI among patients using steroids were 3.33 higher than those not using steroids. Patients who were exposed to different antifungal medication had 72% lower odds to develop IFI.

OBJECTIVE: Breast cancer survivors do not engage in appropriate levels of physical activity, despite the known benefits of such activity. This study aims to describe physical-activity levels and the barriers to it in a group of Puerto Rican breast cancer survivors, as well as detailing their preferences for an intervention. METHODS: Participants who finished their chemotherapy and/or radiotherapy for breast cancer at least 4 months prior to the study were included. Demographic, anthropometric, and clinical data were obtained. The Godin Leisure-Time Exercise Questionnaire (GLTEQ) and questionnaires on exercise self-efficacy, barriers to self-efficacy, modeling, and social support were filled out by study participants. Data on access to exercise equipment and preferences regarding a physical-activity intervention were collected. Descriptive statistics and correlation analyses were performed. RESULTS: Fifty breast cancer survivors were recruited. Almost all the participants reported that they did not engage in any kind of strenuous physical activity (94%), with more than three fourths (76%) reporting that they did not even participate in any kind of moderate physical activity. The GLTEQ score was associated with barriers to selfefficacy, while the association with exercise self-efficacy approached significance (p = 0.055). Nearly half of the patients (44%) had access to exercise equipment. Preferred methods for the delivery of physical-activity interventions were participating in group settings (72%) and receiving material in the postal mail (44%). CONCLUSION: The study described herein reports on the low levels of physical activity being practiced by a group of Puerto Rican breast cancer survivors, despite the fact that many of them had access to exercise equipment and facilities. Further studies aimed at understanding breast cancer survivors' barriers to physical activity and at developing culturally competent interventions to increase the levels of such activity are warranted.

PURPOSE: Physical activity (PA) has a myriad of benefits for breast cancer survivors, including a reduced risk of cancer recurrence. Latinas are less physically active than are women in the general population and little is known about Latina breast cancer survivors' levels of PA or their beliefs related to PA. We conducted a survey of 50 Puerto Rican (PR), 50 Mexican-American (MA) and 50 non-Hispanic white (NHW) breast cancer survivors to investigate similarities and differences in PA and social cognitive theory (SCT) constructs associated with PA. METHODS: We collected information on current PA using the Godin Leisure Time Exercise Questionnaire (GLTEQ); comorbidities; anthropometric measures of body mass index [BMI (kg/m(2))] and waist-to-hip (W:H) ratio; and SCT measures, including exercise self-efficacy, exercise barriers self-efficacy, modeling and social support from friends and family. Descriptive statistics, one-way analysis of variance of differences between groups and regression models of the predictors of PA were performed. RESULTS: Survivors from the three groups were similar in age (M = 56.8, SD = 11.0), BMI (M = 29.0, SD = 5.7) and co-morbidity (M = 2.09, SD = 1.69). Survivors differed in PA (p < 0.001), self-efficacy (p = 0.05), modeling (p = 0.03) and social support from family (p = 0.05). Social support from family member and exercise barriers self-efficacy were predictors of PA. CONCLUSIONS: Consistent with published studies, Hispanic breast cancer survivors self-report that they are less physically active than are non-Hispanic whites. SCT variables associated with PA differ among Hispanic subgroups and non-Hispanic whites. Further research is warranted in order to understand determinants of physical activity for specific ethnic breast cancer survivors.
RESUMEN
UNLABELLED: Differentiated thyroid cancer (DTC) can compromise the quality of life of patients. Our purpose is to investigate if the quality of life, in a cohort of patients in Puerto Rico, is affected by the diagnosis and/or treatment modalities received for DTC. METHODS: This is a cross-sectional study of 75 subjects with DTC. A Spanish version of the University of Washington Quality of Life Questionnaire was used, including multiple aspects of physical and social functioning. Descriptive and bivariate analysis between domain scores and variables of interest were performed. RESULTS: 82.7% of the patients reported that their health was the same or better than it was before treatment. The mean composite score obtained was 82.3, reflecting an overall little effect on quality of life. Patients diagnosed with DTC at an age of > or =45 years reported a significantly better score on the pain domain when compared with those diagnosed earlier (p < 0.05). Patient who received >150 mCi of radioiodine had a tendency towards a worse score on the same domain (p = 0.05). CONCLUSIONS: Our cohort reported an overall minimal effect on the quality of life of patients with DTC. Future treatment strategies should include periodic quality of life evaluations, in order to tailor therapy in this growing population.

OBJECTIVE: In Puerto Rico, leukemia is among the top 10 cancers in terms of incidence and mortality. The aim of the study described herein was to establish the overall leukemia survival rate in Puerto Rico and determine whether there are differences in leukemia survival by type of health insurance coverage. METHODS: Data for adult patients (aged > or = 20 years) diagnosed with leukemia were provided by the Puerto Rico Central Cancer Registry. The relative survival rates (1, 3, and 5 years) were estimated for leukemia patients (diagnosed from 2004 through 2006) by type of health insurance (government health plan [GHP] or non-government health plan [NGHP]). Relative survival is defined as observed survival in the cohort divided by expected survival in the cohort. A Poisson regression model was used to analyze the relative excess risk of death for both the GHP and the NGHP groups. RESULTS: A total of 516 leukemia patients were eligible for analysis. The overall survival rates of leukemia patients in PR for 1, 3, and 5 years after diagnosis were 55.8%, 40.5%, and 34.7%, respectively. Relative survival rates were lower for patients with GHP (1 year = 52.8%; 3 years = 36.4%; 5 years = 32.2%) than they were in people with NGHP (1 year = 57.5%; 3 years = 42.8%; 5 years = 36.1%). Among patients aged 65+ years, those with GHP had a 1.58-fold (95% CI: 1.11-2.27) higher risk of death than did those patients with NGHP. CONCLUSION: Several factors could explain the disparities observed in leukemia survival rates (as grouped by health insurance status) in PR. Some of them include differences in patterns of healthcare coverage, in delays in treatment, in quality of service, in risk factors, and co-morbidities present in the older population studied.

OBJECTIVE: Colorectal cancer (CRC) is among the most common cancers in Puerto Rico. Few studies have correlated clinical and pathological variables with the overall survival of CRC patients in Puerto Rico. We report the clinical and pathological characteristics of patients who underwent surgical resection at a community hospital in Puerto Rico. METHODS: Demographic and pathological variables of patients who underwent CRC surgery at Hospital del Maestro from 2006 through 2011 were reviewed. Descriptive statistics (mean, range, and frequency) and the Cox proportional hazards model were used to determine the influence of demographic and pathological variables on survival, after adjusting for age. RESULTS: Two hundred and five CRC pathology reports were reviewed. Adenocarcinoma represented the most common pathology (202/205; 98.5%). Females represented 52% of the population (106/202) while males represented 48% (96/202). The median age was 71 years (30-96). The right colon was the most common site of presentation (49.7%; 100/201). Stage III was the most common stage at presentation. The presence of mucin, perineural or lymphatic invasion and tumor size were not related to decreased survival. Being male, having a higher stage at diagnosis, and having a moderately or poorly differentiated tumor were characteristics related to decreased survival. CONCLUSION: This study provides information on clinical and pathological variables and their influence on the overall survival of CRC patients at a community hospital in Puerto Rico. Further research must be performed to identify potential disparities and their influence on the prognosis of this patients.
