RESUMEN
BACKGROUND: With the advent of high-resolution chest imaging, the number of patients diagnosed with multiple primary lung cancers is increasing. For the treatment of multiple lung cancers, a surgical procedure that preserves pulmonary function while ensuring curability is required. METHODS: The study population included 85 patients with synchronous multiple primary lung cancer who received surgical resection between January 2010 and September 2020. Patients with synchronous lung cancer within the same lobe were excluded, and only patients with ≥2 involved lobes were included. The postoperative pulmonary function was examined at 3-6 months after the surgery. RESULTS: Sixty-seven patients had cancers within the ipsilateral lobe, and 18 patients had cancers in bilateral lobes. Seventy-six patients (89.4%) underwent combination surgery with limited resection (e.g., segmentectomy and wedge resection). The preoperative pulmonary functions (mean VC/%VC, mean FEV1 /%FEV1 , and mean %DLCO) were 3.06 L/100.2%, 2.23 L/96.1%, and 117.2%, respectively, and the postoperative pulmonary functions were 2.45 L/81.4%, 1.87 L/81.2%, and 102.6%. In each parameter, the predicted reductions of pulmonary function were almost the same as the predicted values. The 5-year survival rate was 85.0%. The 5-year survival rate according to the most advanced pathological stage was 94.9% for stage I disease, and 62.6% for stage ≥II, which was a significant difference (p < 0.001). CONCLUSIONS: Surgical treatment including limited resection, especially segmentectomy and wedge resection, for synchronous multiple primary lung cancer can preserve pulmonary function while ensuring curability.

PURPOSE: The purpose of this study was to analyze the characteristics, diagnosis and treatment principles and prognosis of multiple primary cancers (MPC). METHODS: A total of 77 patients with MPC admitted in the Central Hospital of Changsha from December 2013 to December 2018 were enrolled in this retrospective analysis. The survival of these 77 patients with complete follow-up data was calculated. RESULTS: There were 77 patients with multiple primary cancers, including 70 patients with double primary cancers, 6 patients with three primary cancers, and 1 patient with four primary cancers. Among the 77 MPC patients, there were 4 synchronous carcinomas (SC), 58 metachronous carcinomas (MC), and 15 unknown cases. The 3, 5, and 10-year overall survival rates of 77 patients with follow-up data were 86.5%, 18.2%, and 12.9%, respectively. The median survival time of 4 SC and 58 MC patients was 12 months and 108 months, respectively. The median survival time was 48.5 months in 23 patients with an interval of less than 5 years, and 108 months in 29 patients with first and second primary cancers whose interval was more than 5 years. The median survival time of 26 patients with second primary lung cancer was 84 months, and that of 23 patients with second primary non-lung cancer was 156 months. CONCLUSIONS: MPCs are more likely to occur in the colorectum, and the prognosis of patients with metachronous cancer is better than that of patients with synchronous cancer. The longer the interval between two cancers, the better the prognosis will be. The prognosis of the second primary non-lung cancer patients is better than that of the lung cancer patients.

BACKGROUND: A large plexiform neurofibroma in patients with neurofibromatosis type I can be life threatening due to possible massive bleeding within the lesion. Although the literature includes many reports that describe the plexiform neurofibroma size and weight or strategies for their surgical treatment, few have discussed their possible physical or mental benefits, such as reducing cardiac stress. In addition, resection of these large tumors can result in impaired wound healing, partly due to massive blood loss during surgery. CASE PRESENTATION: A 24-year-old man was diagnosed with neurofibromatosis type I and burdened with a large plexiform neurofibroma on the buttocks and upper posterior thighs. The patient was 159 cm in height and 70.0 kg in weight at the first visit. Cardiac overload was indicated by an echocardiography before surgery. His cardiac output was 5.2 L/min with mild tricuspid regurgitation. After embolism of the arteries feeding the tumor, the patient underwent surgery to remove the neurofibroma, followed by skin grafting. Follow-up echocardiography, performed 6 months after the final surgery, indicated a decreased cardiac output (3.6 L/min) with improvement of tricuspid regurgitation. Because the blood loss during the first surgery was over 3.8 L, malnutrition with albuminemia was induced and half of the skin graft did not attach. Nutritional support to improve the albuminemia produced better results following a second surgery to repair the skin wound. CONCLUSION: Cardiac overload may be latent in patients with neurofibromatosis type I with large plexiform neurofibromas. As in pregnancy, the body may compensate for this burden. In these patients, one stage total excision may improve quality of life and reduce cardiac overload. In addition, nutritional support is likely needed following a major surgery that results in either an extensive skin wound or excessive blood loss during treatment.

To evaluate quality of life and sexual function of childbearing-age women, affected by uterine fibromatosis undergoing medical treatment with ulipristal acetate. The data obtained by filling the questionnaires European Quality of Life Five-Dimension Scale and modified Female Sexual Function Index, were analyzed to assess UPA usefulness in improving QoL and sexual activity. A total of 139 patients affected by uterine fibromatosis undergoing conservative ulipristal acetate treatment were enrolled in this prospective observational cohort study. Seventy-one women (average age 46.5 years) answered the questionnaires: QoL and sexuality were evaluated before and after ulipristal acetate treatment. 59 patients (83.1%) had an improvement of QoL and general health state, with a reduction of VAS score after ulipristal acetate treatment. EQ-5D-5L showed a statistically significant improvement of usual act impairment, mobility, discomfort, anxiety/depression (p < .0005). There was no difference in personal care management after therapy. Modified FSFI showed a statistically significant improvement (p < .0001) of sexual satisfaction and sexual life. A not statistically significant improvement in dyspareunia was also highlighted. This study provides a clear picture about QoL impact on women and confirms the effectiveness of the ulipristal acetate in improving different aspects of daily and sexual life of patients undergoing medical treatment.

PURPOSE: The extent of liver resection for the optimal treatment of hepatocellular carcinoma (HCC) is debated. The purpose of this study was to compare the impact of anatomic resection (AR) vs. parenchyma-sparing resection (PSR) on disease recurrence and patient survival. METHODS: We retrospectively analyzed patients with HCC who underwent liver resection from January 2001 to August 2015. Patients receiving AR or PSR were compared by a propensity score analysis (PSA) (caliper = 0.1). The primary outcomes were disease-free survival (DFS) and overall survival (OS) rates, and assessed by the Kaplan-Meier method. RESULTS: 455 consecutive patients were evaluated. After PSA 354 patient were studied (177 pairs for each group). The median follow-up time was 28.2 months. The median OS was 47.5 months (95% CI: 30.0-65.9) for AR and 56.5 months (95% CI 33.2-79.6) for PSR (p = 0.169). The median DFS was 29.2 months (95% CI 17.6-40.8) for AR and 24.8 months (95% CI: 15.2-34.2) for PSR (p = 0.337). The multivariate regression model showed that cirrhosis (HR 2.85, 95% CI: 1.53-5.32; p = 0.001), BCLC grade B (HR 4.15, 95% CI: 1.33-12.95; p = 0.014), microvascular invasion (HR 1.55, 95% CI: 1.03-2.31; p = 0.033), presence of satellitosis (HR 1.94, 95% CI: 1.25-3.01; p = 0.003), severe complications (HR 6.09, 95% CI: 2.26-16.40; p > 0.001) were independently associated with poor long-term oncologic outcomes. CONCLUSIONS: The extent of resection did not significantly affect overall and disease-free survival while tumor characteristics and underlying liver function appeared significant determinants.

RATIONALE: Synchronous double malignancies, including carcinoma of the ampulla of Vater and rectal carcinoma, are generally uncommon occurrences in the gastrointestinal tract. PATIENT CONCERNS: The present study report a case of a 37-year-old man who was incidentally found to suffer from carcinoma of the ampulla of Vater and rectal carcinoma. DIAGNOSES: The duodenoscopy was performed and revealed an ulcerated and bulky ampulla of Vater, the biopsy from which revealed a moderate-differentiated adenocarcinoma, A local hospital colonoscopy confirmed a tumor located in rectal 7âcm from the anal margin and biopsy-confirmed poorly differentiated adenocarcinoma. INTERVENTIONS: About such patient treatment, both open and laparoscopic surgery are restricted because of operation complexity, large injury, and poor cosmetic effect. surgery performed using Da Vinci robotic surgical system (DVSS). OUTCOMES: No evidence of recurrence or relapses was found in the first year after surgery. LESSONS: Although sporadic double malignancies are uncommon, they should be considered when evaluating cancer patients. Complex surgery performed by robotic surgery may became surgeon's preferred treatment modality.

OBJECTIVE: To document clinical pattern of retinoblastoma in Pakistani population. METHODS: This retrospective study, which was conducted at Department of Ophthalmology, Dow University of Health Sciences, Karachi, reviewed clinical records of patients with retinoblastoma from 1997 to 2012. Staging of disease was done by referring to retinal diagrams, RetCam images, and first magnetic resonance imaging. Ophthalmic notes, imaging reports and histopathology reports of enucleated eyes established optic nerve involvement. SPSS 21 was used for statistical analysis. RESULTS: Clinical records of 295 patients with retinoblastoma in 403 eyes were reviewed, and male to female ratio was 1.3:1. Retinoblastoma was bilateral in 106(35.93%) patients, while 118(40%) patients had hereditary pattern. Mean age at presentation was 35.98+27.63 months, while mean follow-up was 3±2 months. Leucokoria was the most common presenting feature 173(58.64%) followed by proptosis 72(24.41%). Optic nerve involvement was seen on magnetic resonance imaging or histopathology in 81(20.10%) eyes. Distant metastasis was noted in 32(10.85%) patients on first presentation. Chemotherapy with or without adjuvant treatment was given to 238(80.68%) patients. Enucleation and exentration were performed in 164(40.69%) and 12(2.98%) eyes, respectively. CONCLUSIONS: Most common presenting symptom was leucokoria followed by proptosis. Hereditary retinoblastoma was frequently seen in Pakistani children. .

Schwanomatosis is the third most common form of neurofibromatosis. Schwanomatosis affecting the vagus nerve is particularly rare. In this report, we describe an extremely rare case bilateral vagus nerve schwanomatosis in a 45-year-old male patient. The patient initially presented with bilateral neck tumors and hoarseness arising after thoracic surgery. We performed left neck surgery in order to diagnose and resect the remaining tumors followed by laryngeal framework surgery to improve vocal cord closure and symptoms of hoarseness. Voice recovery was successfully achieved after surgery. An appropriate diagnosis and surgical tumor resection followed by phonosurgery improved patient quality of life in this rare case.

Ultraviolet radiation (UVR) induces skin cancer. The combination of UVR and red tattoos may be associated with increased risk of skin cancer due to potential carcinogens in tattoo inks. This combination has not been studied previously. Immunocompetent C3.Cg/TifBomTac hairless mice (n=99) were tattooed on their back with a popular red tattoo ink. This often used ink is banned for use on humans because of high content of the potential carcinogen 2-anisidine. Half of the mice were irradiated with three standard erythema doses UVR thrice weekly. Time to induction of first, second and third squamous cell carcinoma (SCC) was measured. All UV-irradiated mice developed SCCs. The time to the onset of the first and second tumor was identical in the red-tattooed group compared with the control group (182 vs 186 days and 196 vs 203 days, P=ns). Statistically, the third tumor appeared slightly faster in the red-tattooed group than in the controls (214 vs 224 days, P=.043). For the second and third tumor, the growth rate was faster in the red-tattooed group compared with the control (31 vs 49 days, P=.009 and 30 vs 38 days, P=.036). In conclusion, no spontaneous cancers were observed in skin tattooed with a red ink containing 2-anisidine. However, red tattoos exposed to UVR showed faster tumor onset regarding the third tumor, and faster growth rate of the second and third tumor indicating red ink acts as a cocarcinogen with UVR. The cocarcinogenic effect was weak and may not be clinically relevant.

This article provides an overview of pulmonary veno-occlusive disease (PVOD) and pulmonary capillary hemangiomatosis (PCH), two disorders that challenge clinicians, radiologists, and pathologists because they often mimic pulmonary arterial hypertension (PAH). The article reviews the features that differentiate PVOD and PCH from PAH. The article also describes the overlap of PVOD and PCH, highlighted by recent reports of families diagnosed with PVOD or PCH caused by EIF2AK4 mutations. In addition, the article outlines current approaches to the diagnosis and treatment of PVOD and PCH.

OBJECTIVE: To identify renal function outcomes after robotic multiplex partial nephrectomy (RMxPNx), we reviewed our institutional database at the National Institutes of Health, National Cancer Institute. To our knowledge, we present the largest series of RMxPNx renal function outcomes to date. Robotic partial nephrectomy has been employed for oncologic control and to prevent dialysis dependence in hereditary multifocal renal cell carcinoma conditions. We have termed robotic surgery on a single kidney with three or more lesions a RMxPNx. MATERIALS AND METHODS: We evaluated patients from a prospectively maintained database at a single institution (NIH/NCI) that underwent RMxPNx from 2007 to 2013. Demographic and operative data were compiled with statistical analysis with T test performed to determine renal function outcomes. RESULTS: A total of 54 patients underwent RMxPNx. Mean number of tumors removed was 8.63 (range 3-52). Mean preoperative creatinine and eGFR were 1.02 ± 0.26 mg/dL and 85.4 ± 21.5 mL/min, respectively. Postoperatively, creatinine increased from baseline by 0.45 mg/dL (p < 0.001). Similarly, a mean decrease in eGFR by 24.6 mL/min was observed (p < 0.001). At 3-month follow-up, the creatinine increase from baseline was 0.05 mg/dL (p = 0.10) and mean decrease in eGFR was 3.01 mL/min (p = 0.21). When stratifying based on preoperative CKD stages I-III, similar results were observed. CONCLUSION: Robotic multiplex partial nephrectomy is a safe and feasible approach to patients with multifocal renal masses. These complex surgeries have a demonstrated learning curve, but this minimally invasive approach for nephron-sparing surgery allows patients to preserve renal function where they would otherwise require open surgery or a radical nephrectomy.

PURPOSE: An association between neuroendocrine tumors (NETs) and second primary malignancies (SPMs) has been reported. We have examined the incidence and etiology of SPMs in patients with NETs included in the Neuroendocrine Tumor Association of Andalusia (ATNEA) Registry. METHODS: Data on 111 patients were collected. Sex, age, NET site, chromogranin A levels, neuropeptide secretion and disease stage were compared between NETs with and without SPMs. RESULTS: SPMs were present in 21 patients (18.9 %): five colorectal tumors, four non-small-cell lung cancers, three gastric cancers, two tumors in the small intestine, one hepatocarcinoma, two ovarian tumors, one breast adenocarcinoma, one hypernephroma, one bladder cancer, and one neuroblastoma. SPMs were present in 18 % of patients with a gastrointestinal NET and 22 % of those with a non-gastrointestinal NET. SPMs were found in 23 % of patients with elevated levels of serum chromogranin A, compared to 17 % of patients with normal levels, and in 22 % of patients with functional tumors, compared to 11 % of those with non-functional tumors. Finally, SPMs were observed in 24 % of patients with a local or locoregional tumor but in only 13 % of those with a metastatic tumor. No other differences between patients with and without SPMs were observed. CONCLUSIONS: The percentage of patients with SPMs in the ATNEA Registry is similar to those reported in other series. In our registry, patients with functional NETs and local/locoregional tumors have higher probability of SPMs. The low number of patients, selection bias and other etiologic factors of SPMs may have influenced our results (AU)

OBJECTIVE: To test memory performance and executive functions in patients with childhood craniopharyngioma and hypothalamic involvement. STUDY DESIGN: Using standardized neuropsychological tests, we compared cognitive performance in a group of 15 patients with childhood craniopharyngioma and known hypothalamic involvement and a group of 24 age- and intelligence-matched control subjects. In addition, we compared individual patients' results with normative data to detect abnormal performance in the clinically relevant range. Within the patient group, we further tested whether the grade of hypothalamic involvement had an impact on cognitive performance and quality of life. RESULTS: Relative to healthy controls, the patients demonstrated significantly lower performance scores in tests of memory and executive functioning. On the individual performance level, delayed recall performance was severely impaired in one-third of the patients. Compared with patients with low-grade hypothalamic involvement, those with high-grade hypothalamic involvement showed worse performance in executive functions and reduced functional capabilities for daily life actions, indicating lower quality of life. CONCLUSION: Our findings demonstrate that hypothalamic involvement is related to impairments in memory and executive functioning in patients with childhood craniopharyngioma and indicate that a high grade of hypothalamic involvement is related to worse outcomes.

PURPOSE: Tumors in the carotid bodies may interfere with their function as peripheral chemoreceptors. An altered control of ventilation may predispose to sleep-disordered breathing. This study aimed to assess whether patients with unilateral or bilateral carotid body tumors (uCBT or bCBT, respectively) or bilateral CBT resection (bCBR) display sleep-disordered breathing and to evaluate the global contribution of the peripheral chemoreceptor to the hypercapnic ventilatory response. METHODS: Eight uCBT, eight bCBT, and nine bCBR patients and matched controls underwent polysomnography. The peripheral chemoreflex drive was assessed using euoxic and hyperoxic CO2 rebreathing tests. Daytime sleepiness and fatigue were assessed with the Epworth Sleepiness Scale and the Multidimensional Fatigue Index. RESULTS: All patient groups reported significant fatigue-related complaints, but no differences in excessive daytime sleepiness (EDS) were found. The apnea/hypopnea index (AHI) did not differ significantly between patient groups and controls. Only in bCBT patients, a trend towards a higher AHI was observed, but this did not reach significance (p=0.06). No differences in the peripheral chemoreflex drive were found between patients and controls. CONCLUSIONS: Patients with (resection of) CBTs have more complaints of fatigue but are not at risk for EDS. The presence or resection of CBTs is neither associated with an altered peripheral chemoreflex drive nor with sleep-disordered breathing.

BACKGROUND: Carcinoid tumors are uncommon neuroendocrine tumors that account for less than 1% of gastrointestinal tract malignancies. They have a reported incidence of 1.3 per 100,000. Small bowel carcinoids are the commonest and have the highest incidence of associated second primary malignancies, followed by appendiceal and colorectal carcinoids. The most common second primary malignancy is colorectal adenocarcinoma. CASE SERIES: We report a series of 11 patients observed in the period 2006-2011 with primary gastrointestinal tract cancers and synchronous carcinoids discovered incidentally by the histopathologist in the resected primary cancer specimen. RESULTS: In all patients with synchronous carcinoids and colorectal adenocarcinoma there was a pattern of similar embryonic visceral origin. Is this a paracrine effect from biological peptides produced by the carcinoids?

A methodology to determine the unknown shape of an embedded tumor is proposed. A functional that represents the mismatch between a measured experimental temperature profile, which may be obtained by infrared thermography at skin surface, and the solution of an appropriate boundary problem is defined. Using the Pennes's bioheat transfer equations, the temperature in a section of healthy tissue with a tumor region is modeled by a boundary problem. The functional is related to the shape of the tumor through the solution of the boundary problem, in such a way that finding the minimum of the functional form also means finding the unknown shape of the embedded tumor. The shape derivative of the functional is computed in each node of an approximation of the solution by the method of Finite Elements using similar methods considered by Pironneau [7]. The algorithm presented include an adaptive strategy to improve the error of the objective function. Numerical results with multiple connected tumors are considered to illustrate the potential of the proposed methodology.
