[Show abstract][Hide abstract] ABSTRACT: Superior sulcus tumour (SST) is an uncommon neoplasia whose optimal treatment remains controversial. Usually resected after induction RT or treated with definitive chemo-radiotherapy, it has recently aroused more interest because of preoperative chemo-radiotherapy. Treatment consisted of a platinum-based chemotherapy: carboplatin AUC 5 on days 1 and 22, combined with mitomycin-C 8 mg/m(2) on days 1 and 22, and vinblastine 4 mg/m(2) on days 1, 8, 22 and 29 (MVC) from 1994 to 1999, or combined with navelbine 25mg/m(2) on days 1, 8, 22 and 29 (NC), from 2000 to 2007. Radiotherapy was administered 5 days/week, 30 Gy in 10 fractions on days 22-35 (from 1994 to 1996), or 44 Gy in 22 fractions on days 22-52 (from 1997 to 2007). Surgery was planned after 2-3 weeks since the completion of radiotherapy. Since 1994, 37 pts were treated with induction chemo-radiotherapy, 1 with induction radiotherapy only. Induction chemotherapy: 16 pts had MVC (43%) and 21 NC (57%); induction radiotherapy: 7 patients treated with MVC had 30 Gy/10F, 9 had 44 Gy/22F; all the patients treated with NC had 44 Gy/22F, but 2 of them did not complete radiotherapy because of early death (after 16 Gy/8F) and toxicity (after 38 Gy/19F). Grade 3-4 haematological toxicity of induction chemo-radiotherapy was found in 13 patients (35%); the most frequent non-haematological toxicities were constipation and oesophagitis. One complete, 18 partial and 8 minimal responses/stable disease were observed. Moreover, 1 progression disease and 1 early death occurred. Surgery: 30 upper lobectomies (17 right, 13 left) and 4 segmentectomies, with chest wall resections, were performed (89% resection rate); 4 pts were not operated. Radical resections were achieved in 74% of the patients, with 5 pathologic complete remissions at resection. Twenty-seven patients (71%) had improvement of shoulder/arm pain. Median progression-free survival was 64 weeks and median survival was 148 weeks. The 5-year overall and progression-free survivals were 40% and 29%, respectively. In the multimodality treatment of SST, concurrent carboplatin-based chemotherapy plus radiotherapy were active and feasible without major toxicities. This resulted in high resectability rate and favourable progression-free and overall survival rates.
[Show abstract][Hide abstract] ABSTRACT: Post-transplant lymphoproliferative disorders (PTLD) is a serious complication after solid organ transplantation. Reduction of immunosuppression (RI) alone is not able to control the disease. We report a prospective analysis of 30 patients with PTLD after heart or kidney transplantation. Only 5 of 30 patients, treated solely with RI, obtained a complete response. Five patients were treated heterogeneously; in the remaining 20, the efficacy and safety of a weekly anthracycline-based chemotherapy were assessed. Sixteen patients obtained a complete remission. One death was related to treatment. With a median follow-up of 36 months, 3-year overall survival was 63.3% and 57% for the entire group and the chemotherapy-treated group, respectively. Moreover, 4 second neoplasms were observed in the chemotherapeutic group. In this study, we demonstrated that most PTLD need other treatment than RI and a weekly regimen is manageable and has a favourable impact on long-term survival.
[Show abstract][Hide abstract] ABSTRACT: The hypothesis that increasing cytotoxic dose intensity will improve cancer cure rates is compelling. Although supporting evidence for this hypothesis has accrued for several tumor types, including lymphomas, breast cancer, and testicular cancers, it remains unproven. Small-cell lung cancer is extremely chemo- and radiosensitive, with a response rate of 80% achieved routinely, but few patients are cured by chemoradiotherapy. In this setting, increased cytotoxic dose intensity might improve cure rates. The finding that response rates in small-cell lung cancer correlate with received cytotoxic dose intensity merely confirms that "less is worse" and "more is better." Within conventional ranges, dose intensity can be increased with the support of hematopoietic growth factors and/or by shortening treatments intervals; however, dose intensity could be increased by only 20%-30%, and a survival advantage has not been clearly demonstrated. Given its high chemosensitivity, small-cell lung cancer was one of the first malignancies deemed suitable for increasing dose intensity and even for the use of a megadose with the support of autologous bone marrow transplantation. Some interest is emerging again due to improvements in supportive care, such as the availability of hematopoietic growth factors and peripheral blood progenitor cells.
