RESUMO

PURPOSE: The purpose of this study was to evaluate clinical characteristics and treatment pattern of ovarian clear cell carcinoma (OCCC) in Korea and the role of adjuvant chemotherapy in early stage. MATERIALS AND METHODS: Medical records of 308 cases of from 21 institutions were reviewed and data including age, performance status, endometriosis, thromboembolism, stage, cancer antigen 125, treatment, recurrence, and death were collected. RESULTS: Regarding stage of OCCC, it was stage I in 194 (63.6%), stage II in 34 (11.1%), stage III in 66 (21.6%), and stage IV in 11 (3.6%) patients. All patients underwent surgery. Optimal surgery (residual disease ≤ 1 cm) was achieved in 89.3%. Majority of patients (80.5%) received postoperative chemotherapy. The most common regimen was taxane-platinum combination (96%). Median relapse-free survival (RFS) was 138.5 months for stage I, 33.4 for stage II, 19.3 for stage III, and 9.7 for stage IV. Median overall survival (OS) were not reached, 112.4, 48.7, and 18.3 months for stage I, II, III, and IV, respectively. Early-stage (stage I), endometriosis, and optimal debulking were identified as favorable prognostic factors for RFS. Early-stage and optimal debulking were also favorable prognostic factors for OS. Majority of patients with early-stage received adjuvant chemotherapy. However, additional survival benefit was not found in terms of recurrence. CONCLUSION: Majority of patients had early-stage and received postoperative chemotherapy regardless of stage. Early-stage and optimal debulking were identified as favorable prognostic factors. In stage IA or IB, adding adjuvant chemotherapy did not show difference in survival. Further study focusing on OCCC is required.

RESUMO

PURPOSE: The treatment strategy for elderly patients older than 80 years with diffuse large B-cell lymphoma (DLBCL) has not been established because of poor treatment tolerability and lack of data. MATERIALS AND METHODS: This multicenter retrospective study was conducted to investigate clinical characteristics, treatment patterns and outcomes of patients older than 80 years who were diagnosed with DLBCL at 19 institutions in Korea between 2005 and 2016. RESULTS: A total of 194 patients were identified (median age, 83.3 years). Of these, 114 patients had an age-adjusted International Prognostic Index (aaIPI) score of 2-3 and 48 had a Charlson index score of 4 or more. R-CHOP was given in 124 cases, R-CVP in 13 cases, other chemotherapy in 17 cases, radiation alone in nine cases, and surgery alone in two cases. Twenty-nine patients did not undergo any treatment. The median number of chemotherapy cycles was three. Only 37 patients completed the planned treatment cycles. The overall response rate from 105 evaluable patientswas 90.5% (complete response, 41.9%). Twentynine patients died due to treatment-related toxicities (TRT). Thirteen patients died due to TRT after the first cycle. Median overall survival was 14.0 months. The main causes of death were disease progression (30.8%) and TRT (27.1%). In multivariate analysis, overall survival was affected by aaIPI, hypoalbuminemia, elevated creatinine, and treatment. CONCLUSION: Age itself should not be a contraindication to treatment. However, since elderly patients show higher rates of TRT due to infection, careful monitoring and dose modification of chemotherapeutic agents is needed.

RESUMO

BACKGROUND: Docetaxel/cisplatin (DP) and gemcitabine/cisplatin (GP) are standard treatment regimens for advanced non-small cell lung cancer (NSCLC). In spite of potent efficacy, the conventional 1-day DP is regarded as having more toxicity as compared with GP. There is increasing interest in a biweekly split administration of DP to reduce its toxicity. Hypothesis was that first-line biweekly DP is as safe as GP in the elderly or poor performance status (PS) patients. METHODS: Chemotherapy-naïve patients with advanced NSCLC (IIIB/IV) who were elderly (65<) or PS (ECOG 2) were randomized to DP or GP arm by balancing for ECOG (0-1 vs. 2) and stage (IIIB vs. IV). DP comprised docetaxel (35 mg/m2)/cisplatin (30 mg/m2) iv on days 1 and 8, every 3 weeks. GP comprised gemcitabine (1000 mg/m2)/cisplatin (30 mg/m2) iv on days 1 and 8, every 3 weeks. Chemotherapy lasted up to 4-6 cycles or until progression. Primary endpoint was safety (proportion of grade 3/4 toxicities). Planned sample size was 49 patients in each arm. RESULTS: From November 2009 to August 2012, a total of 99 patients were randomized (DP 50/GP 49) from nine institutions. Adenocarcinoma and squamous cell carcinoma were observed in 62% and 33% of patients, respectively. Toxicity profiles were comparable for both arms and the differences were not statistically significant except for anemia and leucocytopenia. Any grade of anemia (86 vs. 98%) and of leucocytopenia (18 vs. 43%) was more common in the GP arm with statistical significance. Oral mucositis tended to be predominant in the DP arm. Patients in the DP arm (51%) suffered grade 3 or higher toxicities as did 47% in the GP arm (47%). The most common grade 3 or higher toxicities were as follows: In the DP arm, neutropenia (8%), leucopenia (8%), anemia (4%), pneumonia with normal ANC (4%) and febrile neutropenia (2%) were observed. In the GP arm, anemia (15%), neutropenia (15%), pneumonia with normal ANC (4%), thrombocytopenia (4%) and leucopenia (2%) were observed. The best overall response rates (CR + PR) for the DP and GP arms were 20.0 and 21% with no CR, respectively, and disease control rates (CR + PR + SD) were 70.0 and 76%, respectively. Median progression-free survival and median overall survival were 3.7 and 14.9 months in the DP arm and 5.6 and 20.8 months in the GP arm, respectively. CONCLUSION: This study showed that DP is similar to GP in terms of efficacy and toxicity in treatment of elderly or poor performance patients. Both regimens showed similar grade 3/4 toxicities with different profiles.

RESUMO

BACKGROUND: Osmotic release oral system (OROS) hydromorphone is a potent, long-acting opioid analgesic, effective and safe for controlling cancer pain in patients who have received other strong opioids. To date, few studies have examined the efficacy of hydromorphone for pain relief in opioid-naive cancer patients. OBJECTIVES: A prospective, open-label, multicentre trial was conducted to determine the efficacy and tolerability of OROS hydromorphone as a single and front-line opioid therapy for patients experiencing moderate to severe cancer pain. METHODS: OROS hydromorphone was administered to patients who had not previously received strong, long-acting opioids. The baseline evaluation (visit 1) was followed by two evaluations (visits 2 and 3) performed two and 14 weeks later, respectively. The starting dose of OROS hydromorphone was 4 mg/day and was increased every two days when pain control was insufficient. Immediate-release hydromorphone was the only accepted alternative strong opioid for relief of breakthrough pain. The efficacy, safety and tolerability of OROS hydromorphone, including the effects on quality of life, and patients' and investigators' global impressions on pain relief were evaluated. The primary end point was pain intensity difference (PID) at visit 2 relative to visit 1 (expressed as %PID). RESULTS: A total of 107 patients were enrolled in the present study. An improvement in pain intensity of >50% (≥50% PID) was observed in 51.0% of the full analysis set and 58.6% of the per-protocol set. The mean pain score, measured using a numerical rating scale, was significantly reduced after two weeks of treatment, and most adverse events were manageable. Quality of life also improved, and >70% of patients and investigators were satisfied with the treatment. CONCLUSIONS: OROS hydromorphone provided effective pain relief and improved quality of life in opioid-naive cancer patients. As a single and front-line treatment, OROS hydromorphone delivered rapid pain control.
