RESUMEN
BACKGROUND: The analysis of regional lymph nodes is particularly relevant in patients with stage II colorectal cancer, in whom the role of adjuvant chemotherapy remains unclear. The aim of this study was to assess the relationship between number of examined lymph nodes and survival in patients with stage IIA (pT3N0M0) colorectal cancer, and to determine the optimal number of lymph nodes that should be examined. METHODS: The study group included all the surgically-treated colorectal cancer patients in stage IIA (n = 657) who were identified through the population-based Cancer Registry of the Province of Modena (Northern Italy), during the period 2002-2006. RESULTS: The median number of harvested lymph nodes was 19 (range 1-68). Considering, as a reference point, patients with 12 or less lymph nodes, subjects with n ≥ 20 lymph nodes examined showed, in univariate analysis, a significantly higher cancer specific (p = 0.01) and relapse-free survival (p = 0.003). The results were confirmed by multivariate analysis (Cox model). CONCLUSION: The result suggests that colorectal cancer patients in stage IIA with n ≥ 20 lymph nodes examined exhibit better survival when compared with subjects in whom fewer lymph nodes were examined. The number of 20 lymph nodes is the essential requirement for an oncologic resection of the large bowel.

BACKGROUND: This Italian multicentric retrospective study aimed to investigate the possible changes in outcomes of patients undergoing surgery for gastrointestinal cancers during the COVID-19 pandemic. METHOD: Our primary endpoint was to determine whether the pandemic scenario increased the rate of patients with colorectal, gastroesophageal, and pancreatic cancers resected at an advanced stage in 2020 compared to 2019. Considering different cancer staging systems, we divided tumors into early stages and advanced stages, using pathological outcomes. Furthermore, to assess the impact of the COVID-19 pandemic on surgical outcomes, perioperative data of both 2020 and 2019 were also examined. RESULTS: Overall, a total of 8250 patients, 4370 (53%) and 3880 (47%) were surgically treated during 2019 and 2020 respectively, in 62 Italian surgical Units. In 2020, the rate of patients treated with an advanced pathological stage was not different compared to 2019 (P = 0.25). Nevertheless, the analysis of quarters revealed that in the second half of 2020 the rate of advanced cancer resected, tented to be higher compared with the same months of 2019 (P = 0.05). During the pandemic year 'Charlson Comorbidity Index score of cancer patients (5.38 ± 2.08 vs 5.28 ± 2.22, P = 0.036), neoadjuvant treatments (23.9% vs. 19.5%, P < 0.001), rate of urgent diagnosis (24.2% vs 20.3%, P < 0.001), colorectal cancer urgent resection (9.4% vs. 7.37, P < 0.001), and the rate of positive nodes on the total nodes resected per surgery increased significantly (7 vs 9% - 2.02 ± 4.21 vs 2.39 ± 5.23, P < 0.001). CONCLUSIONS: Although the SARS-CoV-2 pandemic did not influence the pathological stage of colorectal, gastroesophageal, and pancreatic cancers at the time of surgery, our study revealed that the pandemic scenario negatively impacted on several perioperative and post-operative outcomes.

PURPOSE: To describe the outcome of a patient with a rare primitive uterine pPNET and to perform a review of the available data in literature, leading the clinicians to better face this rare disease. METHODS: We have rescued data regarding the multidisciplinary treatment of pPNET from the PUBMED database, highlighting also issues regarding the pathogenesis and the genetic landscape of the ESFTs (Ewing Sarcoma Family of Tumors). RESULTS: Ewing sarcoma and primitive neuroectodermal tumors (PNETs) are small round cell tumors presenting with different degrees of neuroectodermal differentiation. PNETs are further divided into central PNET and peripheral PNET (pPNET). Since pPNETs share the same genetic background of Ewing Sarcomas, they are considered to belong to the Ewing Sarcoma Family of Tumors (ESFTs). Multimodality treatment currently represents the best choice to offer to the affected patients. CONCLUSION: Although pPNETs are generally diagnosed in children and young adults, an elderly woman aged 85 years came to our attention after a diagnosis of uterine pPNET. Her medical history is presented here, along with a literature review of the subject, highlighting the main biological, pathological and clinical features, with a hypothesis about the possible future therapeutic approaches for these rare malignancies.
RESUMEN
BACKGROUND/AIMS: The aim of this study was to evaluate the survival benefit of adjuvant chemotherapy with etoposide, leucovorin and 5-fluorouracil (ELF) in gastric cancer patients undergoing previous surgery with a curative intent. METHODOLOGY: The clinical outcome of 49 patients with resected gastric cancer treated with adjuvant chemotherapy was compared with that of 85 surgically treated historical controls who did not receive any adjuvant treatment. The chemotherapy regimen consisted of six cycles of daily 1-hour intravenous infusions of folinic acid 100 mg/m2 and 5-FU 400 mg/ m2, and a 2-hour infusion of etoposide 100 mg/m2, for three days every 28 days. RESULTS: The 5-year relapse-free survival was 32% in the adjuvant arm and 27% in the control arm (p = 0.6). At the last follow-up, there were 32 deaths in the adjuvant arm and 60 in the control arm. The median duration of survival was respectively 23 and 19 months, and the 5-year survival rates were 34% and 29% (p = 0.4). The chemotherapy was well tolerated. CONCLUSIONS: Our data suggest that ELF adjuvant treatment is a safe and well tolerable combination chemotherapy in patients with resected gastric cancer, but it does not seem to improve prognosis in comparison with historical controls.

BACKGROUND: The role of salvage chemotherapy in advanced non-small cell lung cancer (NSCLC) is still controversial, but the recent development of a number of active antineoplastic agents has created new possibilities for disease management. The aim of this study was to evaluate the activity and safety of weekly docetaxel treatment in patients with advanced NSCLC previously treated with two chemotherapy regimens. PATIENTS AND METHODS: The study involved 26 patients with histologically documented stage IIIB, IV or recurrent metastatic NSCLC previously treated with two non-taxane based-chemotherapy regimens. They all received docetaxel 25 mg/m(2)/week administered as a 1-h infusion in an outpatient setting with corticosteroid premedication. RESULTS: Fourteen of the 26 patients (54%) had distant metastases and 12 (46%) chest-localised disease. Six patients (23%; confidence interval: 9.8-44.1%) showed a partial response, 8 (31%) stable disease, and 12 (46%) progressive disease. The median time to progression was 4 months (range 2-8), and the median survival was 7+ months (range 3-13+). There were no statistically significant differences between the global quality of life scores recorded at baseline and those recorded after subsequent cycles. The treatment was very well tolerated. CONCLUSION: The results of this study suggest that weekly low-dose docetaxel is effective, well tolerated and maintains a relatively good quality of life in patients with advanced NSCLC previously exposed to two chemotherapy regimens.

PURPOSE: To assess the activity and safety of combined folinic acid (FA), 5-fluorouracil (5-FU) and mitomycin C (MMC) in metastatic breast cancer patients previously treated with at least two chemotherapy regimens. PATIENTS AND METHODS: A total of 104 consecutive patients were enrolled for treatment with FA 100 mg/m(2) plus 5-FU 400 mg/m(2) i.v. on days 1-5, and MMC 3 mg/m(2) on days 3-5 (FFM). The cycles were repeated every 21 days until progression, severe toxicity or patient refusal. RESULTS: Of the 104 patients, 96 were evaluable for response and toxicity. The overall response rate was 43% (95% confidence interval 32.8-53.2%); 40 patients achieved stable disease (42%) and 15 progressed (15%). In a retrospectively defined subgroup of patients with clinical resistance to taxanes (12 patients) or anthracyclines (14 patients), the response rate was 42%. The median time to progression was 8 months (3-18 months), and the median overall survival was 10.5+ months (2-36 months). The most common treatment-related adverse events were stomatitis, neutropenia, nausea/vomiting and diarrhea. Stomatitis, neutropenia and thrombocytopenia were the only grade 4 treatment-related adverse events, and occurred in no more than 3% of patients. CONCLUSION: The tested FFM regimen seems to offer a valid option for patients with metastatic breast cancer who have been pretreated with two or more chemotherapeutic lines or who have failed on regimens containing anthracyclines or taxanes.

This randomized study compared the efficacy of epirubicin-based adjuvant chemotherapy on the disease-free interval (DFI) and overall survival of patients with high-risk soft-tissue sarcomas. After curative surgery, 43 of the 88 enrolled patients were assigned to surgery with or without radiotherapy and 45 to surgery plus chemotherapy (26 epirubicin, 19 epirubicin + ifosfamide) with or without radiotherapy. The trial closed prematurely because of poor patient accrual. There was a statistical significant difference in the 5-year disease-free survival of the patients receiving adjuvant chemotherapy with or without radiotherapy (69%) and that of those treated with surgery with or without radiotherapy (44%) ( p= 0.01). The 5-year survival of the patients treated with adjuvant chemotherapy with or without radiotherapy was 72% as against 47% of those treated with surgery with or without radiotherapy ( p= 0.06). The power of the study was 0.65 for both the DFI and overall survival. The results of the study suggest a possible advantage of epirubicin-based adjuvant chemotherapy in patients with soft-tissue sarcoma at high risk of relapse.

OBJECTIVES: To investigate the prognostic value of some conventional bone markers and a number of other factors in terms of the survival of patients with hormone-resistant prostate cancer and bone metastases treated with chemotherapy. METHODS: The data of 141 patients were analyzed to verify the influence of the following factors on survival: bone-alkaline phosphatase, type I collagen propeptide, the carboxyterminal telopeptide of type I collagen, the urinary calcium/creatinine ratio, patient age, Karnofsky performance status, pathologic grade, duration of response to primary hormonal therapy, prostate-specific antigen, hemoglobin, lactate dehydrogenase, and extent of bone disease. RESULTS: When all the variables were simultaneously analyzed using the multivariate proportional hazard model, only Karnofsky performance status (P <0.005) and duration of response to primary hormonal therapy (P <0.0001) remained statistically significant. CONCLUSIONS: The results of this study suggest that bone-alkaline phosphatase, type I collagen propeptide, the carboxyterminal telopeptide of type I collagen, and the urinary calcium/creatinine ratio are not prognostic of survival in patients with hormone-resistant prostate cancer and bone metastases treated with chemotherapy.

OBJECTIVE: The aim of this study was to evaluate the activity and tolerability of docetaxel in patients with hormone-resistant prostate cancer previously exposed to chemotherapy. METHODS: We enrolled 27 patients with hormone-resistant prostatic cancer that had progressed during first-line chemotherapy. The primary end-point was palliative response defined as a 2-point reduction in the 6-point present pain intensity scale, and an improvement in Karnofsky performance status of one 10-point category. The treatment consisted of weekly docetaxel 25 mg/m(2) body surface area administered by means of a 1-hour intravenous infusion with corticosteroid premedication. RESULTS: The primary criterion of palliative response was met in 13 patients (48%) after eight treatment cycles; its median duration was 6 months (range 1-8). Mean global quality of life improved in 8 and 10 patients after respectively four and eight treatment cycles. After a median follow-up of 8 months, 21 patients had died: the median survival was 9+ months (range 2-18). Weekly docetaxel was very well tolerated: grade 3 neutropenia occurred in 1 patient and grade 3 anemia in 2. CONCLUSIONS: Weekly low-dose docetaxel is an effective and well-tolerated treatment for patients with hormone-resistant prostate cancer previously exposed to chemotherapy.
