RESUMEN

PURPOSE: Active surveillance (AS) and adjuvant chemotherapy (AC) with carboplatin are valid alternatives for managing stage I seminoma, and most relapses can be cured with cisplatin-based chemotherapy. However, some reports suggest that AC may modify the classical pattern of recurrences. METHODS: We analyzed all relapses observed in a series of 879 patients with stage I seminoma included in 4 consecutive studies of the Spanish Germ Cell Cancer Group. After a median follow-up of 67 months, recurrences were detected in 56/467 (12%) low-risk cases on AS and 13/412 (3%) high-risk cases after AC (p < 0.001). The objective was to describe clinical features, treatment and outcome. Univariate comparisons were performed between both groups. RESULTS: No significant differences were found between relapses on AS and those after AC in terms of time to relapse (13 vs 17 months), size (26 vs 27 mm), location (retroperitoneum in 88% vs 85%), and method of detection (computed tomography in 77% vs 69%). Treatment consisted of chemotherapy (etoposide + cisplatin ± bleomycin) in 89% and 92%, respectively. Late relapses (after > 3 years) were seen in 11% vs 7.7% (p = NS) and second or successive recurrences in 1.8 vs 23% (p < 0.05). With a median follow-up of 130 moths, two patients died of seminoma-unrelated causes (AS group) and the rest are alive and disease-free. CONCLUSION: In the setting of a risk-adapted treatment of stage I seminoma, the administration of two courses of AC in patients with tumor size > 4 cm and/or rete testis invasion is associated with a higher incidence of second recurrences but does not significantly modify the pattern of relapses or their outcome.

RESUMEN

The goal of this article is to provide recommendations about the management of kidney cancer. Based on pathologic and molecular features, several kidney cancer variants were described. Nephron-sparing techniques are the gold standard of localized disease. After a randomized trial, sunitinib could be considered in adjuvant treatment in high-risk patients. Patients with advanced disease constitute a heterogeneous population. Prognostic classification should be considered. Both sunitinib and pazopanib are the standard options for first-line systemic therapy in advanced renal cell carcinoma. Based on the results of two randomized trials, both nivolumab and cabozantinib should be considered the standard for second and further lines of therapy. Response evaluation for present therapies is a challenge.

RESUMEN

Soft-tissue sarcomas are uncommon and heterogeneous tumors of mesenchymal origin. A soft-tissue mass that is increasing in size, greater than 5 cm, or located under deep fascia are criteria for suspicion of sarcoma. Diagnosis, treatment, and management should preferably be performed by a multidisciplinary team in reference centers. MRI and lung CT scan are mandatory for local and distant assessment. A biopsy indicating histological type and grade is needed previous to the treatment. Wide surgical resection with tumor-free tissue margin is the primary treatment for localized disease. Radiotherapy is indicated in large, deep, high-grade tumors, or after marginal resection not likely of being improved with reexcision. Neoadjuvant and adjuvant chemotherapy improve survival in selected cases, usually in high-grade sarcomas of the extremities. In the case of metastatic disease, patients with exclusive lung metastasis could be considered for surgery. First-line treatment with anthracyclines (or in combination with ifosfamide) is the treatment of choice. New drugs have shown activity in second-line therapy and in specific histological subtypes.

RESUMEN

Testicular cancer represents the most common malignancy in males aged 15-34 years and is considered a model of curable neoplasm. Maintaining success, reducing treatment burden, and focusing on survivorship are then key objectives. Inguinal orchiectomy is the first recommended maneuver that has both diagnostic and therapeutic aims. Most patients are diagnosed with stage I disease (confined to the testicle). Close surveillance and selective, short-course adjuvant chemotherapy are accepted alternatives for these cases. In patients with more advanced disease (stages II and III), 3-4 courses of cisplatin-based chemotherapy (according to IGCCCG risk classification) followed by the judicious surgical removal of residual masses represent the cornerstone of therapy. Poor-risk patients and those failing a first-line therapy should be referred to specialized tertiary centers. Paclitaxel-based conventional chemotherapy and high-dose chemotherapy plus autologous hematopoietic support can cure a proportion of patients with relapsing or refractory disease.

RESUMEN

BACKGROUND: Brain metastases of testicular germ cell tumor (TGCT) are a rare event. Prognostic is poor and there is not much evidence on optimal management of these patients. PATIENTS AND METHODS: A review of case records of germ cell tumor patients within the Spanish Germ Cell Cancer Group data base from 1994 to 2012 was conducted. RESULTS: Thirty-three out of 6,200 cases (0.5 %). Nineteen patients (57 %) group 1: synchronous, 13 (40 %) group 2: metachronous and only one developed brain metastasis during cisplatin-based chemotherapy (excluded from the analysis). Median serum BHCG levels at initial diagnosis was higher in group 1, whereas elevated AFP serum levels were more common in group 2. Histology in the primary tumor: chorionic carcinoma for group 1 versus embryonal carcinoma for group 2. Mainly solitary brain metastasis in group 2 (54 versus 21 %, respectively). The median overall survival from the diagnosis of central nervous system involvement was 16 months for group 1 (CI 95 % 13.9-18) and 23 months (95 % CI 0-165) for group 2 (log rank p = 0.84). Long-term survivors were practically identical in the two groups (38.9 % group 1 versus 38.5 % group 2). Regardless of the timing of brain metastasis, those patients that achieved complete response to the treatment had better survival (log rank p 0.003). CONCLUSION: Although some distinctive clinical characteristics have been found between patients with synchronous versus metachronous brain metastasis from TGCT, the timing of brain metastasis did not seem to have prognostic influence, but due to the retrospective nature of the analysis and the results should be interpreted with caution.

RESUMEN

OBJECTIVE: To provide an outpatient facility to improve the management of chemotherapy toxicity in cancer patients. PATIENTS AND METHODS: We set up an oncology acute toxicity unit (OATU) to improve toxicity management. A telephone helpline was the initial contact which filters out inappropriate non-toxicity-related events. Patients were provided an information booklet describing the possible side effects of the chemotherapy and the helpline telephone number. A specialist nurse received the calls and consulted the doctor if necessary. Depending on requirements, the patient's problem was resolved by telephone, or a consultation visit at the OATU was arranged. RESULTS: Between February 1999 and August 2001, 1126 patients made 2007 contacts with the OATU. The most common tumours were breast (26%), colorectal (20%) and lung (20%). The telephone helpline was used in 87% of contacts and 37% were considered inappropriate. Of the 1263 appropriate contacts, the most frequent chemotherapy schedules that had been administered were 5FU-leucovorin (11.2%) and CMF (10.4%). The most frequent side effects were fever (35.5%), diarrhoea (18.5%), mucositis (16.2%) and emesis (13%). The problem was resolved by telephone in 48% of cases and 52% required attendance in the OATU, of which 40% required hospital admission, i.e., 21.1% of the initial appropriate helpline contacts. The most frequent reason was Grade 3-4 neutropenic fever (56.5%). CONCLUSIONS: The OATU enables prompt and efficient access of patients to medical oncology facilities in the event of toxicity due to chemotherapy. Unnecessary emergency room use is avoided while oncology outpatient and hospitalisation facilities are optimised.
