PURPOSE: To study the use of chemotherapy for Merkel cell carcinoma (MCC) of the skin. PATIENTS AND METHODS: Twenty-five cases of MCC were treated at the London Regional Cancer Center between 1987 and 1997. Thirteen cases treated with chemotherapy were reviewed with 191 cases from the literature. RESULTS: At presentation, 24 patients had localized skin lesions (stage I) and one had locoregional involvement (stage II). Among the nine cases with recurrent nodal disease, six had chemotherapy as a component of salvage treatment. They were all free of disease at a median of 19 months (range, 12 to 37 months). In contrast, two patients who had salvage radiotherapy alone died of disease. Overall survival (OS) and disease-free survival (DFS) were 59% and 43%, respectively, at two years. Median OS and DFS were 29 months (range, 1 to 133 months) and 9 months (range, 1 to 133 months), respectively. Nodal disease developed in 12 (50%) of 24 patients with stage I disease, and distant metastases developed in six (25%) of 24. Including those from the literature, there were 204 cases treated with chemotherapy. Cyclophosphamide/doxorubicin (or epirubicin)/vincristine combination ± prednisone was the most commonly used chemotherapy regimen (47 cases), with an overall response rate of 75.7% (35.1% complete, 35.1% partial, and 5.4% minor responses). Etoposide/cisplatin (or carboplatin) was the next most commonly used regimen (27 cases), with an overall response rate of 60% (36% complete and 24% partial responses). The difference in response rate was not statistically significant (P = .19). Among the 204 cases, there were seven (3.4%) toxic deaths. CONCLUSION: Chemoradiation for locally recurrent or advanced disease may be an option for patients with a good performance status.

Abstract Purpose Early stage Merkel cell carcinoma (MCC) is a rare and aggressive primary skin cancer. The standard of care for MCC is broad excision and adjuvant external beam radiation therapy (EBRT). However, for some patients, anesthesia is contraindicated, while others run the risk of serious aesthetic sequelae. In such cases, exclusive radiotherapy is an interesting alternative to surgery. Though limited data is available, this study evaluates exclusive radiotherapy for MCC, using data from the largest retrospective study to date. Methods All patients who were followed in our center between 1989 and 2019 for histologically proven early stage MCC were included in the study. They were treated either by surgery with a 2-cm clear margin followed by adjuvant radiotherapy (RT) or by exclusive RT. Survival rates with adjuvant and exclusive EBRT were analyzed using Cox model and Fine and Gray model depending on the type of survival. p value < 0.05 was considered significant. Results Eighty-four patients treated for MCC were included. Fifty-three of them (63.1%) were treated by exclusive RT, and 31 (36.9%) had surgical excision followed by adjuvant RT. Local relapse rate was 13.7% (95% CI 8.0–43.7) in the RT monotherapy group (group A) and 25.8% (95% CI 10.3–56.2) in the surgery + RT group (group B) (p = 0.42). No statistical difference was found for nodal relapse (p = 0.81), metastatic relapse (p = 0.10), disease free survival (p = 0.83) or overall survival (p = 0.98). Conclusion Our study suggests that exclusive radiotherapy for early Merkel cell carcinoma leads to a similar oncological outcome as combined treatment, with fewer aesthetic sequelae. The approach is interesting for elderly patients with comorbidities or patients for whom surgery would cause significant functional or aesthetic sequelae.

Background Patients with locally advanced, recurrent or metastatic solitary fibrous tumour are often treated with bevacizumab and temozolomide based on the clinical efficacy reported in a case series of 14 patients. Given the rarity of solitary fibrous tumour, large trials are not feasible. We report the efficacy of this regimen based on a population-based analysis. Methods This was a population-based retrospective, multi-centre analysis using patient data from a provincial cancer registry and treatment database. Cases from June 2006 through October 2016 were identified for patients receiving bevacizumab and temozolomide for locally advanced, recurrent or metastatic solitary fibrous tumour or hemangiopericytoma, which is sometimes used to describe tumours arising from the meninges. The primary outcome was overall response rate. Secondary outcomes included time to response, progression free survival and overall survival estimated using the Kaplan–Meier method. Results Fourteen patients were identified: median age 59 (range 44–70), male 78.6%. Diagnoses were solitary fibrous tumour in 10 (71.4%) and hemangiopericytoma in four (28.6%), with metastatic disease in 10 (72.7%) patients. The most common primary sites were meninges in four (28.6%) and pelvis in three (21.4%) patients. The median follow-up was 15.5 months, with median treatment of four months. Overall response rate was 21.4% (no complete response, 3 partial response), with median time to response of four months. Median progression free survival, six-month progression free survival and overall survival were 17 months, 65.0%, and 45 months, respectively. Conclusions Efficacy of bevacizumab and temozolomide in solitary fibrous tumour appeared to be similar to that previously reported. Our findings confirmed that bevacizumab and temozolomide is an effective and tolerated treatment for this patient population.

Abstract Purpose: To evaluate efficacy, safety, Disease-Free Survival (DFS) and Overall Survival (OS) in patients with indolent non-Hodgkin’s lymphoma (NHL) treated with chemotherapy vs. immunotherapy vs immunochemotherapy as first-line therapy, an up-date report. Methods: Patients with indolent NHL were randomized to receive: (A) Rituximab x 6/w, (B) CNOP (cyclophosphamide, mitoxantrone, vincristine and prednisone) x 6 or (C) R-CNOP x 6, at standard doses. Results: 195 patients were included, 183 are evaluable for OS and toxicity (A:62, B:55 and C:66), 144 are evaluable for overall response rate (ORR) and DFS (A:53, B:41 and C:50). Clinical characteristics: 89 male (45.6%), mean age 59±14 (±SD), 148 (75.9%) in stage (III/IV), without significant differences between groups. Overall Response Rate (CR+PR) was: A: 84.9%, B:83.4% and C:90% (P=0.545). Neutropenia grade 3/4 was more frequent in the chemotherapy groups: A: 4.8%, B: 23.6% and C:18.2% (P=0.001) as it was the infectious toxicity (grade 2/4): A:4.8%, B:5.5% and C:15.2% (P=0.07). DFS at 24 months was: A 68%, B:65% and C:70%, (P=0.93) and the OS was A:87%, B:84% and C:78%. P=0.89. Conclusions: We did not find any important differences, between groups, regarding the Overall Response Rate, Disease Free Survival and Overall Survival at 24 months. However, single agent rituximab was better tolerated, with less toxicity in comparison with the chemotherapy containing groups. Based on these findings, it maybe reasonable to use immunotherapy only, as first-line therapy for patients with indolent NHL.

15520 Background: The optimum radiosensitizing dose and schedule of gemcitabine for squamous cell carcinoma of head and neck are not known. The objectives of this study were to evaluate the efficacy and toxicity of weekly gemcitabine as a radiosensitizer concurrent with radical radiotherapy in locally advanced head and neck cancer. Method: Thirty-nine patients with stage III or IV B inoperable carcinoma of head and neck were enrolled. Eligible patients had histopathologically confirmed squamous cell carcinoma with age between 18–70 years. Patients had a KPS >70 with an adequate marrow, hepatic and renal function. No prior chemotherapy or radiotherapy was allowed. Patients with nasopharyngeal, glottic or sub-glottic cancer were excluded. Gemcitabine 150 mg/m2 or a total dose not exceeding 200 mg was given on day 1,8,15,22,29, and 36 during radiation treatment. Gemcitabine was infused in 200 ml of normal saline in 2 hours and radiation was delivered two hours after the completion of gemcitabine infusion. Conventional fractionation was used to deliver a total dose of 66 Gy. CTC version 2.0 of NCI and RTOG/EORTC Late Radiation Morbidity Scoring Scheme were used for evaluation of toxicity and RECIST was used for response evaluation. Results: Only 35 patients were considered evaluable for response. Complete response was seen in 8 (22.9%) (95% CI; 10.4–40.1%), partial response in 25 (71.4%), with an overall response rate of 94.3% (95% CI; 80.8–99.3%). All the thirty-nine patients were evaluable for toxicity. Grade 3 and 4 mucositis was seen in 28 (71.8%) and 2 (5.1%) patients respectively. Grade 3 pharyngeal toxicity was seen in 6 (15.4%). One patient developed pharyngo-cutaneous fistula. Despite vigorous symptomatic and supportive care acute toxicities led to treatment interruption in 16 (41%) of patients. Conclusion: Weekly gemcitabine at a dose of 150mg/m2 concurrent with radiation therapy gives a high overall response rate and a high rate of acute toxicity. No significant financial relationships to disclose.

e21038 Background: Up to 45% of stage I-II melanomas will relapse within 5 years, and some relapses occur more than 10 years after surgical resection. Little is known about the differences in tumor characteristics, including immunogenicity, of early- vs. late-relapsing melanoma, or the implication of these differences in response to PD-1 inhibition. Methods: A retrospective cohort study was conducted to compare time from definitive treatment of localized melanoma to relapse with response to pembrolizumab. Patients with prior stage I-II melanoma who relapsed, and then treated with pembrolizumab, were included in the study. Time to relapse was compared with overall response rate. Results: Among the study population, 66 patients initially presented with early stage disease that relapsed within the study period. The median time to relapse was 5 years (range 0.5-33 years, interquartile range 7.25, Q1 = 2, Q2 = 9.25). 9 patients (14%) relapsed within 2 years of surgery; these patients had a higher overall response rate to pembrolizumab than late-relapsing patients with marginal significance (88% vs 50%, p = 0.056). The difference became less significant when patients who relapsed before or after 5 years (70% vs 47%, respectively, p = 0.20), and before or after 10 years (64% vs 45%, p = .31). Conclusions: Patients with early-relapsing melanoma had higher ORR to pembrolizumab than patients with late-relapsing disease, with early relapse defined as earlier than 2 years from definitive surgical intervention. Late relapsing tumors may harbor mechanisms of resistance to immune checkpoint inhibition.
