A prospective study of cisplatin-based combination chemotherapy in advanced germ cell malignancy: role of maintenance and long-term follow-up.

Two hundred fifty-three patients with advanced germ cell malignancy received initial chemotherapy with cisplatin, vinblastine, and bleomycin followed by surgical resection of residual masses if possible. Patients achieving complete remission (CR) were prospectively randomized to receive 6 months maintenance therapy with vinblastine or no further treatment. CR was achieved in 183 patients (72%) and a further eight patients (4%) had complete resection of residual viable malignancy (no evidence of disease [NED]). Pretreatment factors having a significant adverse influence on response by univariate analysis included extragonadal origin of the tumor, poor performance status, advanced lung or lung and abdominal disease, and elevated serum levels of human chorionic gonadotropin (HCG) and alpha-fetoprotein (AFP) greater than 1,000 ng/mL. Multivariate regression analysis indicated the independent prognostic factors of significance were advanced lung or advanced lung and abdominal disease, total tumor diameter greater than 10 cm, and a serum level of HCG greater than 1,000 ng/mL. Of the toxicities encountered, myelosuppression was significant, being exacerbated by radiotherapy, and seven deaths occurred from septicemia. Bleomycin pulmonary toxicity occurred in 46% of patients and was severe in 4%, resulting in eight deaths. With a median follow-up of 64 months, relapses have occurred in 25 patients with no significant difference between those patients receiving or not receiving maintenance vinblastine. Eight of these relapses occurred beyond 1 year and four beyond 2 years of follow-up. Presently, 68% of the total patient population is alive and disease-free, with 84% of the CR and NED patients alive and 81% alive and disease-free. It is concluded that with prolonged follow-up, vinblastine maintenance therapy does not improve treatment outcome. Moreover, late relapses occur, cautioning against premature pronouncements of cure.

Abstract BACKGROUND Limited data is available in intracranial nongerminomatous germ cell tumors (NGGCTs) in Chinese population. Here we aimed to retrospectively assess the clinical-pathological and prognostic factors of NGGCTs in a single large institution in China. METHODS From June 2003 to December 2018, 111 consecutive NGGCTs were treated in Guangdong Sanjiu Brain Hospital, China. RESULTS The median follow-up was 36.2 months (range, 1.2 to 131.2 months). Three-year EFS and OS for 111 NGGCTs patients were 78.5%±4.5% and 82.8%±4.0%, respectively. 98 patients received CSI plus boost yielded better survival than those who received reduced-volume radiotherapy or no radiotherapy (3y OS, 86.7% vs. 51.4%, p=0.007). Patients had at least four cycles of chemotherapy were strongly associated with improved 3-year OS, compared to those received less than 4 cycles (94.1% vs. 63.6%, p＜0.001). There was no significant difference in survival of patients stratified by age, surgery, hydrocephalus, as well as tumor diameter. Multivariate analysis identified chemotherapy cycles less than 4 was the only prognostic factor that conferring a worse OS (p=0.003). Patients both received CSI and at least 4 courses of chemotherapy were correlated with lower incidence of relapse (p=0.044). CONCLUSIONS Multimodal approach including CSI and enough courses of chemotherapy was effective and should be recommended for the treatment of newly diagnosed NGGCTs in Chinese population.

PURPOSE In a previously reported randomized Southeastern Cancer Study Group (SECSG) trial, three cycles of chemotherapy were found to be equivalent to four cycles in patients with favorable-prognosis germ-cell cancer. We have conducted a follow-up analysis of patients treated at Indiana University (Indianapolis, IN) to compare long-term survival between the two groups and to examine factors associated with survival. PATIENTS AND METHODS Sixty-nine patients with minimal-stage and 49 patients with moderate-stage disseminated germ-cell tumors were randomized to either three or four courses of bleomycin, etoposide, and cisplatin (BEP) administered every 3 weeks. Median follow-up time is 10.1 years (range, 7 months to 12.6 years). Ninety-two percent of patients have an actual follow-up time of > 5 years, and 97.5% of patients have an actual follow-up time of > 3 years. RESULTS Survival analysis shows no significant difference between the two treatment groups in terms of overall (P = .80) or disease-free (P = .93) survival. Several clinical variables were examined by univariate analysis; only serum human chorionic gonadotropin (HCG) had an impact on survival. There were two disease-related deaths in 104 patients with HCG < or = 1,000 mIU/mL and five disease-related deaths in 14 patients with HCG greater than 1,000 mIU/mL (P < .001). Ninety-eight percent (95% CI, 95.2 to 100) of patients with favorable prognosis germ-cell tumor with an initial HCG of < or = 1,000 mIU/mL are alive without evidence of disease at 5+ years. CONCLUSION With long-term follow-up, there is no statistically significant difference in survival between three or four cycles of BEP chemotherapy in patients with favorable prognosis germ-cell carcinoma. Serum HCG elevation of greater than 1,000 mIU/mL is a significant predictor of poor outcome in patients with otherwise good-risk disease.

590 Background: An aging society has come, and “Frailty” is becoming increasingly important in surgery. Recently, clinical frail scale (CFS), which is simple criteria for frailty, has been reported to be useful for prognostic prediction of non-cardiac surgery (Ann Surg. 2018). Herein we report a new knowledge about frailty for patients with hepatocellular carcinoma (HCC) undergoing hepatectomy. Methods: Eighty-one patients over 75 years who underwent hepatectomy for HCC between 2007 and 2018 were enrolled in this study. Frailty was diagnosed as CFS≥4, and patient were divided into 2 groups, frailty (n = 17) and no frailty (n = 64). Clinicopathological factors were compared between 2 groups. Results: Patients’ background, such as age, gender, preoperative comorbidity, and liver function showed no significant difference between 2 groups. Regarding tumor factors, frailty group showed significant larger tumor diameter, more advanced stage (p < 0.05) and tendency of high PIVKA-II (p = 0.15) compared with no frailty group. Frailty group showed significant high CRP level (p < 0.01), high modified Glasgow prognostic score (mGPS, p = 0.04) and tendency of high neutrophil-lymphocyte ratio (NLR, p = 0.14). Frailty group also showed tendency of higher rate of postoperative complication (p = 0.11) and longer postoperative hospital stay (p = 0.09). Overall and disease-free survival rate were significantly worse in frailty group (p = 0.03). In univariate analysis for overall survival, AFP≥10, PIVKA-II≥400, frailty and mGPS high (1, 2) were prognostic factor. Multivariate analysis revealed that frailty was independent prognostic factor. In univariate analysis of disease-free survival, only frailty was detected as prognostic factor. Conclusions: Frailty is an independent prognostic factor for HCC patients who underwent hepatectomy.

e14533 Background: To determine impact of modern chemotherapy regimens after pulmonary metastasectomy from colorectal cancer (CRC). Methods: A total of 122 consecutive patients who curatively resected for pulmonary metastases of CRC in eleven oncology centers were retrospectively analysed between January 2000 and April 2012. Results: Of 122 patients, 108 who received chemotherapy with fluoropyrimidine-based (n = 12), irinotecan-based (n = 56) and oxaliplatin-based (n = 40) combinations were analyzed. Among these, 52 patients received bevacizumab (BEV) while 56 did not (NoBEV). With a median follow-up of 14 months after metastasectomy, median recurrence-free survival (RFS) was 17 months, overall survival (OS) was not reached. Three and 5-years OS rates were 66% and 53%, respectively. There was no significant difference among cytotoxic regimens in respect to RFS and OS. Similarly, no significant difference was seen between BEV and NoBEV arms in respect to OS and RFS. In univariate analysis prior liver metastasectomy (p = 0.045), positive pulmonary margin (p = 0.028), disease-free interval < 12 months (p = 0.013), and KRAS mutation (0.009) were negative significant prognostic for RFS. Thoracic pathological lymphatic involvement (p = 0.006) and higher prethoracotomy carcinoembryonic antigen (p = 0.038) were negative significant prognostic for OS. In multivariate analysis, positive pulmonary margin was the only negative independent prognostic for RFS, while thoracic lymphatic involvement was the only negative independent prognostic for OS. Conclusions: Chemotherapy type and addition of bevacizumab have no impact on both RFS and OS in the adjuvant setting following complete resection of colorectal pulmonary metastases.

The Impact

Background:Telemedicine was widely utilised to complement face-to-face (F2F) care in 2020 during the COVID-19 pandemic, but the impact of this on patient care is poorly understood.Objectives:To investigate the impact of telemedicine during COVID-19 on outpatient rheumatology services.Methods:We retrospectively audited patient electronic medical records from rheumatology outpatient clinics in an urban tertiary rheumatology centre between April-May 2020 (telemedicine cohort) and April-May 2019 (comparator cohort). Differences in age, sex, primary diagnosis, medications, and proportion of new/review appointments were assessed using Mann-Whitney U and Chi-square tests. Univariate analysis was used to estimate associations between telemedicine usage and the ability to assign a diagnosis in patients without a prior rheumatological diagnosis, the frequency of changes to immunosuppression, subsequent F2F review, planned admissions or procedures, follow-up phone calls, and time to next appointment.Results:3,040 outpatient appointments were audited: 1,443 from 2019 and 1,597 from 2020. There was no statistically significant difference in the age, sex, proportion of new/review appointments, or frequency of immunosuppression use between the cohorts. Inflammatory arthritis (IA) was a more common diagnosis in the 2020 cohort (35.1% vs 31%, p=0.024). 96.7% (n=1,444) of patients seen in the 2020 cohort were reviewed via telemedicine. In patients without an existing rheumatological diagnosis, the odds of making a diagnosis at the appointment were significantly lower in 2020 (28.6% vs 57.4%; OR 0.30 [95% CI 0.16-0.53]; p<0.001). Clinicians were also less likely to change immunosuppressive therapy in 2020 (22.6% vs 27.4%; OR 0.78 [95% CI 0.65-0.92]; p=0.004). This was mostly driven by less de-escalation in therapy (10% vs 12.6%; OR 0.75 [95% CI 0.59-0.95]; p=0.019) as there was no statistically significant difference in the escalation or switching of immunosuppressive therapies. There was no significant difference in frequency of follow-up phone calls, however, patients seen in 2020 required earlier follow-up appointments (p<0.001). There was also no difference in unplanned rheumatological presentations but significantly fewer planned admissions and procedures in 2020 (1% vs 2.6%, p=0.002). Appointment non-attendance reduced in 2020 to 6.5% from 10.9% in 2019 (OR 0.57 [95% CI 0.44-0.74]; p<0.001), however the odds of discharging a patient from care were significantly lower in 2020 (3.9% vs 6%; OR 0.64 [95% CI 0.46-0.89]; p=0.008), although there was no significance when patients who failed to attend were excluded. Amongst patients seen via telemedicine in 2020, a subsequent F2F appointment was required in 9.4%. The predictors of needing a F2F review were being a new patient (OR 6.28 [95% CI 4.10-9.64]; p<0.001), not having a prior rheumatological diagnosis (OR 18.43 [95% CI: 2.35-144.63]; p=0.006), or having a diagnosis of IA (OR 2.85 [95% CI: 1.40-5.80]; p=0.004) or connective tissue disease (OR 3.22 [95% CI: 1.11-9.32]; p=0.031).Conclusion:Most patients in the 2020 cohort were seen via telemedicine. Telemedicine use during the COVID-19 pandemic was associated with reduced clinic non-attendance, but with diagnostic delay, reduced likelihood of changing existing immunosuppressive therapy, earlier requirement for review, and lower likelihood of discharge. While the effects of telemedicine cannot be differentiated from changes in practice related to other aspects of the pandemic, they suggest that telemedicine may have a negative impact on the timeliness of management of rheumatology patients.Disclosure of Interests:None declared.

BackgroundThere is no consensus regarding the best treatment option for unruptured aneurysms of the posterior communicating artery (PCom) presenting with oculomotor nerve palsy (ONP). We aimed to assess predictors of ONP recovery in a multicenter series of consecutive patients.Materials and methodsA retrospective review of prospective databases in three tertiary neurosurgical centers was carried out, selecting patients with ONP caused by unruptured PCom aneurysms, treated by surgical clipping or embolization, between January 2006 and December 2013. Patient files and imaging studies were used to extract ophthalmological assessments, treatment outcomes, and follow-up data. Predictors of ONP recovery during follow-up were explored using univariate and multivariate analyses.ResultsWe identified 55 patients with a median ONP duration before treatment of 11 days (IQR 4.5–18); the deficit was complete in 27 (49.1%) and incomplete in 28 (50.9%) cases. Median aneurysm size was 7 mm (IQR 5–9). Twenty-four (43.6%) patients underwent surgical clipping and 31 (56.4%) embolization as the primary treatment. Overall, ONP improved in 40 (72.7%) patients and persisted/recurred in 15 (27.3 %). Surgery, interval to complete treatment <4 weeks, aneurysm recurrence during follow-up, and retreatment during follow-up were significantly correlated with ONP outcome in the univariate analysis. In the multivariate analysis, independent predictors of ONP improvement were interval to complete treatment <4 weeks (OR 5.15, 95% CI 1.37 to 23.71, p=0.015) and aneurysm recurrence during follow-up (OR 0.1, 95% CI 0.02 to 0.47, p=0.003).ConclusionThere was no significant difference in ONP recovery between surgical clipping and embolization. The best predictor for ONP recovery was timely, complete, and durable aneurysm exclusion.

PURPOSE This study analyzed a large group of patients with testicular germ cell cancer in complete remission, who relapsed more than 2 years after completion of treatment. PATIENTS AND METHODS A review of all patients treated at Indiana University Medical Center from 1979 through 1992 for late relapse was conducted. Eighty-one patients were treated for late relapse of testicular cancer. Forty-seven patients relapsed more than 5 years after successful management of their initial disease. RESULTS At initial diagnosis, 35 patients had clinical stage I, 18 stage II, and 28 stage III disease. Twenty-three of 35 stage I, all 18 stage II, and all 28 stage III patients were treated by chemotherapy before their late relapse. The median follow-up duration of patients post-management of late relapse was 4.8 years. Twenty-one patients (25.9%) are continuously disease-free. Nineteen of these 21 patients had surgical resection of carcinoma or teratoma as a component of their therapy. Of sixty-five patients treated for late relapse by chemotherapy, 17 (26.2%) had a complete response, but only two have been continuously disease-free with chemotherapy alone. These two never received prior chemotherapy. CONCLUSION Late relapse of testis cancer is more common than previously thought. Surgery is the preferred mode of therapy. Chemotherapy has only modest success in this entity, in contrast to the excellent results in de novo germ cell tumors. Patients treated for testicular germ cell cancer need annual follow-up evaluations throughout their life due to the possibility of late relapse.

Abstract Abstract 1056 Poster Board I-78 Introduction: We previously showed that a prolonged myelosuppressive maintenance chemotherapy was superior to S-HAM as a postremission therapy in patients > 16 years of age with AML after a TAD-HAM double induction therapy and TAD consolidation chemotherapy with regard to relapse-free survival (RFS) and borderline significance of the overall survival (OS) in responding patients (Buchner et al., JCO 2003, 21:4496-4504). Here we present long-term follow-up data with a median follow-up of 7.9 years from diagnosis and 7.1 years from the date of complete remission. Patients and Methods: Eight hundred thirty-two patients (median age, 54 years; range, 16 to 82 years) with de novo AML were upfront randomized in the AMLCG1992 study of the German AML Co-operative Group to receive 6-thioguanine, cytarabine, and daunorubicin (TAD) plus cytarabine and mitoxantrone (HAM; cytarabine 3 g/m2 [age < 60 years] or 1 g/m2 [age ≥ 60 years] x 6 (HAM in patients ≥ 60 years only in case of blast persistence on day 16 of therapy) induction, TAD consolidation, and monthly maintenance with cycles of cytarabine combined with either daunorubicin (course 1), 6-thioguanine (course 2), cyclophosphamide (course 3), and again 6-thioguanine (course 4), and restarting with course 1 for 3 years, or to receive TAD-HAM-TAD and one course of intensive consolidation with sequential HAM (S-HAM) with cytarabine 1 g/m2 (age < 60 years) or 0.5 g/m2 (age ≥ 60 years) x 8 instead of maintenance. Results: A total of 576 patients (69.2%) achieved a complete remission (CR) those were 294 of 429 (68.5%) patients randomized to receive maintenance and 282 of 403 (70.0%) patients randomized to receive intensive consolidation S-HAM (p=n.s.). 190 patients received maintenance therapy as intended and 135 patients received an intensive consolidation therapy as intended. This prolonged follow-up analysis verified the superior relapse-free survival in all patients in the maintenance arm (10-year RFS 30.0 ± 5.6 versus 19.9 ± 6.1 %, p = 0.015). Stratified by age, the 10-year RFS was superior in younger patients < 60 years (36.9 ± 7.1 versus 25.2 ± 8.0 %, p = 0.038) and borderline significant in elderly patients (17.2 ± 4.5 versus 6.8 ± 6.2 %, p = 0.075). A subgroup analysis of known risk groups (lactate dehydrogenase (LDH) level < 700U/l versus ≥ 700U/l at diagnosis, cytogenetic risk profile, bone marrow blasts on day 16 after the start of the induction therapy) revealed a superior RFS in the subgroup of patients with LDH level > 700 U/l at diagnosis (33.5 ± 12.3 versus 18.2 ± 9.5 %, p = 0.043). This superior RFS also translated into a superior 10-year relapse-free interval (RFI) of all responding patients in the maintenance arm (35.7 ± 6.3 versus 27.6 ± 5.9 %, p = 0.015) with borderline significance in younger patients (42.9 ± 7.4 versus 35.0 ± 7.4 %, p = 0.053) and a significant difference in elderly patients (20.6 ± 10.0 versus 8.4 ± 7.5 %, p = 0.043). In this updated analysis, there was a trend, but no significant difference in the OS (maintenance arm: 10-year OS 24.3 ± 4.8, intensive consolidation arm: 19.7 ± 4.7 %, p = 0.148), and we verified a trend for a better OS in responding patients for the maintenance arm (10-year OS in responding patients 33.6 ± 7.5 versus 28.5 ± 6.2 %, p = 0.093). The event-free survival (EFS) also showed a trend towards better EFS in the maintenance arm (10-year EFS 20.7 ± 4.2 versus 14.8 ± 4.1 %, p = 0.082) which was significant in elderly patients (10-year EFS 10.5 ± 5.5 versus 3.9 ± 3.7 %, p = 0.044). Discussion: This updated analysis with a long-term follow-up of median 7.9 years from diagnosis and 7.1 years from CR verified the superior RFS and the trend for enhanced OS in responding patients. These results suggest the superiority of a prolonged monthly myelosuppressive maintenance therapy as compared to intensive consolidation S-HAM after TAD-HAM induction and TAD consolidation. Disclosures: No relevant conflicts of interest to declare.

372 Background: The diagnosis of UMP is used for dysplastic mucinous tumors that are difficult to classify as clearly benign or malignant. Given the rarity of this tumor, management of these patients is unclear. Methods: All patients with a pathologic diagnosis of an appendiceal mucinous UMP who underwent evaluation at a single institution between September 1993 and July 2009 were retrospectively reviewed. Patient demographics, operative findings, pathology, tumor markers, procedures performed, recurrence, overall survival, and disease-free survival were determined. Results: Of 688 patients with appendiceal neoplasms, 62 (9%) patients (pts) were identified as having UMP. Initial procedures included: appendectomy - 45, colectomy - 11, cytoreduction - 2, and other - 4. Median follow-up was 43.2 months (range 2-184 mos). Median overall survival (OS) was 11.5 years (range 2-184 mos). Median disease-free survival (DFS) has not been reached. There was a trend towards improved DFS in patients who are: female, < 65 years of age, or have mucin confined to the appendix or its serosal surface. Clinicopathologic factors associated with a significantly worse overall DFS included elevated serum CEA (3.6 years, p = 0.0129) and CA-125 (4.16 years, p = 0.0288). DFS at 8 years follow-up in patients with a normal CEA was as follows: 100% if mucin confined to lumen of the appendix, 90% if mucin confined to serosa, and 69% if mucin was in an extra-appendiceal location. 15 patients developed recurrent disease and had an OS of 4.6 years after recurrence.
