<bold>Introduction:</bold> Cervical cancer is most common cancer in the rural and second most common in urban areas of our country. It accounts for 16% of all cancers. There are various clinical, Paper Submission Datepathological and radiological factors which dictate the prognosis of these cancer cervix patients. The present study evaluates clinical, pathological and radiological prognostic factors in cancer cervix treated with concurrent chemoradiation. <bold>Material and Methods:</bold> A total of 32 patients seen between 2012 and 2014 patients planned concurrent chemoradiation were evaluated in terms of clinical (age, stage, Hb% and HPV Paper Publication Date infection), pathological (histopathology type and subtype, grade, mitotic index, lymph-July 2016 vascular invasion and necrosis) and radiological (parametrial extension, disease dimension, lymph node, hydronephrosis and vascularity of tumour) prognostic factors. After pre-DOI treatment evaluation patient was planned for 3 Dimentional-Conformal Radiotherapy (50Gy/25#/5 weeks) with concurrent chemotherapy (Cisplatin 35mg/m<sup>2</sup>) followed by 3 applications of Intracavitary radiotherapy (6Gy/fraction) with 6 months follow up. Response was accessed according to WHO response criteria and univariate analysis was done using chi-square test. <bold>Results:</bold> Clinical factors: Age – better disease free survival in older patients (p value=0.003), stage - Lower stage had better survival (for stage Ib-IIa vs stage IIb p value = 0.003 and for stage Ib vs. IIIb p value = 0.0005), Hb% - 57% patients with Hb <10g/dl had recurrence at end of 6 months (p value=0.00001), HPV – High recurrence with HPV presence. Pathological factors like high Mitotic Index had more residual disease (p=0.0009), grade - No statistical significance. Radiological factors- volume of disease - 35 % patients with volume of disease > 6 cm had disease at end of 6 months, hydronephrosis - 40 % patient with hydronephrosis had recurrence (p value = 0.0005) at end of 6 months follow up and vascularity of tumour showed statistically no difference. <bold>Conclusion:</bold> Hb <10%, HPV infection, Mitotic index (3-5/HPF), stage IIIB, pelvic nodes were concluded as the independent poor prognostic factors.

Background. Adult granulosa cell tumors (AGCTs) are the most common sex cord-stromal tumors. Unlike epithelial ovarian tumors, they occur in young women and are usually detected at an early stage. The aim of this study was to report the clinical and pathological characteristics of AGCT patients and to identify the prognostic factors. Methods. All cases of AGCTs, treated at Salah Azaïz Institute between 1995 and 2010, were retrospectively included. Kaplan-Meier’s statistical method was used to assess the relapse-free survival and the overall survival. Results. The final cohort included 31 patients with AGCT. The mean age was 53 years (35–73 years). Patients mainly presented with abdominal mass and/or pain (61%, n=19). Mean tumor size was 20 cm. The majority of patients had a stage I disease (61%,  n=19). Two among 3 patients with stage IV disease had liver metastasis. Mitotic index was low in 45% of cases (n=14). Surgical treatment was optimal in almost all cases (90%, n=28). The median follow-up time was 14 years (1–184 months). Ten patients relapsed (32%) with a median RFS of 8.4 years (6.8–9.9 years). Mean overall survival was 13 years (11–15 years). Stage I disease and low-to-intermediate mitotic index were associated with a better prognosis in univariate analysis (resp., p=0.05 and p=0.02) but were not independent prognostic factors. Conclusion. GCTs have a long natural history with common late relapses. Hence, long active follow-up is recommended. In Tunisian patients, hepatic metastases were more frequent than occidental series. The prognosis remains good and initial staging at diagnosis is an important prognostic factor.

11118 Background: Neoadjuvant chemotherapy is a standard treatment in stage III breast cancer. Prognostic factors can help to identify patients (pts) with high risk of recurrence. The aim of this study was to assess several prognostic factors after a long follow-up, in stage III breast cancer pts, treated with neoadjuvant chemotherapy. Methods: We evaluated 126 pts with stage III breast cancer that participated in a phase-II randomized trial of neoadjuvant 5-fluorouracil, doxorubicin and cyclophosphamide (FAC every 21 days) compared with cyclophosphamide, methotrexate and 5-fluorouracil (CMF days 1 and 8 every 28). Chemotherapy was administered for three cycles prior to definitive surgery and radiotherapy, and then for six cycles as adjuvant. Response was assessed by WHO criteria. Results: The median age was 52 years (range 24-75). Median follow-up was 4.5 years (range 0.2-16.4), disease free survival (DFS) 4.8 years and overall survival (OS) 6.4 years. Results of the phase-II study showed no difference in efficacy between groups. Univariate analysis showed that the number of pathologically involved lymph nodes (pLN), pathologic response and estrogen and progesterone receptor status correlated with DFS and OS. Number of pLN was the only prognostic factor with statistical significance in Cox regression test for both, DFS and OS (P=0.0004 and P=0.0006, respectively). In a subgroup analysis of pts with pLN, we found no difference in survival when we compared FAC with CMF. Conclusions: The prolonged follow-up of this study provides a unique opportunity to evaluate factors that predict long-term outcomes. After 16 years of follow-up, the number of pLN remains the most powerful predictor of survival. The subset of pts with pLN had similar survival regardless of the regimen used.

The objective of this study was to determine the clinicopathologic prognostic factors in adult granulosa cell tumors of the ovary. A retrospective review of the records of patients of granulosa tumors who were treated at our institute over a period of 10 years (1995–2005) was done. Clinical, pathologic, and follow-up data were collected. A total of 34 patients who were treated during this period were subjected to analysis. Cox univariate analysis and Wilcoxon's test for multivariate analysis were used as part of the SPSS software for examining the data. It was found that optimal cytoreduction (P= 0.02), presence of nuclear atypia (P< 0.001), and increased mitoses (P= 0.03) were the three factors that impacted significantly on survival. Age, stage of the tumor, parity, and size of the tumor had no significant effect on survival. Patients who received chemotherapy had a better median disease-free survival than those who did not (60 vs 48 months), but this did not reach statistical significance (P= 0.08). Optimal cytoreduction, nuclear atypia, and increased mitoses are the statistically significant prognostic factors and may be used for selecting patients for adjuvant therapy.

Abstract Background The prognosis of patients with gastrointestinal stromal tumors (GISTs) is generally evaluated at the time of diagnosis but does not reflect the survival dynamics of patients in the future. Therefore, the purpose of this article was to evaluate the conditional survival (CS) of Chinese patients with GISTs after radical resection. Methods This retrospective study included 451 patients who underwent radical surgery for GISTs. A Cox proportional hazard model was used to evaluate the prognostic factors of disease-free survival (DFS). The 3-year conditional DFS (CDFS3) of patients who survived for x years was expressed as CDFS3=DFS(x + 3)/DFS(x). Results The traditional 3-year DFS rate decreased gradually from 94.0% at 3 years to 77.3% at 7 years, while the CDFS3 rate increased from 94.0 to 95.2% over the survival time of the patients. In addition, classic clinicopathological prognostic factors had different effects on CDFS3, with changes observed in survival time, but these effects were only slight or moderate (|d|<0.5). Although multivariate analysis showed that age, sex, mitotic index and tumor rupture were independent risk factors for DFS at baseline, all adverse prognostic factors, except for the mitotic index, lost their predictive significance at 5 years after operation. When the Modified NIH criteria were included, the risk staging was found to be an independent risk factor for recurrence or death. Time-dependent Cox regression analysis showed that the modified NIH criteria independently affected the recurrence or death of GIST patients within 2 years after operation. Conclusion CS provides detailed dynamic survival information about Chinese patients with primary resected GISTs. The mitotic index is of great clinical significance for the monitoring and follow-up of patient populations with a high risk of tumor recurrence or death until 5 years after surgery.

Background: Determination of the prognostic factors which affects the mortality and morbidity in COVID-19 patients, has an importance in terms of planning the treatment and follow-up strategy. Material and Method: Patients who had COVID-19 diagnosis via microbiologically and/or radiologically between March and October 2020 in a tertiary-care university hospital were recorded retrospectively. Only adult patients (≥18 years) with clinical spectrum of moderate, severe and critical illness were included in the study according to National Institutes of Health (NIH) guideline. A p value of less than 0.05 was considered significant. Ethical committee approval was given from the Uludag University with decision number 2020-22/11. Also, the permission from Republic of Turkey, Ministry of Health was given. Results: A total number of 257 patients were included in the study. 30-day mortality rate was recorded as 14.4%. In univariate analysis; age, chronic renal failure, malignancy, cerebrovascular disease, number of comorbidities >2, dyspnea, cough, NIH severe and critical illness, oxygen saturation, respiratory rate, systolic and diastolic blood pressure, qSOFA, GCS, MEWS, SOFA, CURB-65, CCI, CRP, procalcitonin, CK, D-dimer, lymphocyte and thrombocyte levels, neutrophile-to-lymphocyte ratio, AST, albumin, hemoglobin, CK-MB, fibrinogen, LDH and potassium levels were found as statistically significant (p<0.05). In logistic regression analysis one point increase of SOFA (p<0.001, OR:1.861, 95%CI:1.403-2.468) and CURB-65 scores (p=0.002, OR:2.484, 95%CI:1.401-4.406) were found as statistically significant for 30-day mortality. In mortal patients, there were significant difference between the baseline, day 3, 7 and 14 results of D-dimer (p=0.01), Ferritin (p=0.042), leucocyte (p=0.019) and neutrophile count (p=0.007). Conclusion: In our study, SOFA and CURB-65 scores on admission were associated with mortality and these score systems might be useful tools for the prognosis in COVID-19 patients.In addition to this, D-dimer, Ferritin, leucocyte and neutrophile counts were significantly increased during the follow up in patients with mortality.

Abstract INTRODUCTION Renal cell carcinoma (RCC) represents 3% of overall malignant neoplasms in adults. However, its aetiology has not been clearly established. Although surgery represents the cornerstone in treatment, recurrence postoperative rates are around 20-30%, what implies prognostic factors search must be mandatory in order to help to plan de follow-up and the different adjuvant therapy possibilities available in case they were necessary. MATERIAL AND METHODS A retrospective observational study was carried out in 110 patients who underwent radical nephrectomy between 2004 and 2018, with the aim of identifying possible prognostic factors of recurrence of RCC after these surgeries. Preoperative data (epidemiological, comorbidities and laboratory tests), surgical, pathological and variables related to follow-up were taken into account. A univariate and multivariate analysis were performed, using chi-square test and logistic regression, respectively. RESULTS The median follow-up time was 53.5 months (SD = 35.8), time in which 19 patients had a recurrence of RCC after radical nephrectomy (17.2%). Histopathological items such as the surgical piece size, the nodal and microvascular invasion, the renal sinus invasion and the presence of necrosis in the surgical piece were associated with RCC recurrence in the univariate analysis, while only the presence of necrosis in the surgical piece showed a significant result in the multivariate analysis (p = 0.004). CONCLUSIONS Histopathological analysis, highlighting the presence of necrosis in the histological sample, was proved to be the main risk factor of RCC recurrence.

Purpose NCCTG (North Central Cancer Treatment Group) N9831 is the only randomized phase III trial evaluating trastuzumab added sequentially or used concurrently with chemotherapy in resected stages I to III invasive human epidermal growth factor receptor 2–positive breast cancer. Patients and Methods Patients received doxorubicin and cyclophosphamide every 3 weeks for four cycles, followed by paclitaxel weekly for 12 weeks (arm A), paclitaxel plus sequential trastuzumab weekly for 52 weeks (arm B), or paclitaxel plus concurrent trastuzumab for 12 weeks followed by trastuzumab for 40 weeks (arm C). The primary end point was disease-free survival (DFS). Results Comparison of arm A (n = 1,087) and arm B (n = 1,097), with 6-year median follow-up and 390 events, revealed 5-year DFS rates of 71.8% and 80.1%, respectively. DFS was significantly increased with trastuzumab added sequentially to paclitaxel (log-rank P < .001; arm B/arm A hazard ratio [HR], 0.69; 95% CI, 0.57 to 0.85). Comparison of arm B (n = 954) and arm C (n = 949), with 6-year median follow-up and 313 events, revealed 5-year DFS rates of 80.1% and 84.4%, respectively. There was an increase in DFS with concurrent trastuzumab and paclitaxel relative to sequential administration (arm C/arm B HR, 0.77; 99.9% CI, 0.53 to 1.11), but the P value (.02) did not cross the prespecified O'Brien-Fleming boundary (.00116) for the interim analysis. Conclusion DFS was significantly improved with 52 weeks of trastuzumab added to adjuvant chemotherapy. On the basis of a positive risk-benefit ratio, we recommend that trastuzumab be incorporated into a concurrent regimen with taxane chemotherapy as an important standard-of-care treatment alternative to a sequential regimen.

AbstractMale breast cancer (MBC) is a rare disease. The few studies on MBC reported conflicting data regarding survival outcomes compared to women. This study has two objectives: to describe the characteristics of a single-cohort of MBC and to compare overall survival (OS) and disease-free survival (DFS) between men and women using the propensity score matching (PSM) analysis. We considered MBC patients (n = 40) diagnosed between January 2004 and May 2019. Clinical, pathological, oncological and follow-up data were analyzed. Univariate analysis was performed to determine the prognostic factors on OS and DFS for MBC. We selected female patients with BC (n = 2678). To minimize the effect of the imbalance of the prognostic factors between the two cohorts, the PSM method (1:3 ratio) was applied and differences in survival between the two groups were assessed. The average age of MBC patients was 73 years. The 5-year OS and DFS rates were 76.7% and 72.2% respectively. The prognostic factors that significantly influenced OS and DFS were tumor size and lymph node status. After the PSM, 5 year-OS was similar between MBC and FBC (72.9% vs 72.3%, p = 0.70) while we found a worse DFS for MBC (72.2% vs 91.4%, p  = 0.03). Our data confirmed previous reported MBC characteristics: we found a higher risk of recurrence in MBC compared to FMC but similar OS. MBC and FMC are different entities and studies are needed to understand its epidemiology and guide its management.

e20507 Background: It is reported that about 20% of patients with resected NSCLC adenocarcinoma harbor an EGFR driver mutation in the United States. Up to the recent approval of osimertinib in the adjuvant setting for resected EGFR + NSCLC based on the ADAURA trial, routine molecular profiling of early-stage lung cancer had not been standard of care. We hypothesize that there is a significant proportion of patients with resected adenocarcinoma with unknown EGFR status who could benefit from treatment that are missed with our current testing practices. Methods: We performed a retrospective analysis of Stage IB-IIIA lung adenocarcinomas resected at the University of Miami from 2014 to 2019. Eligible patients were identified from the Cancer Registry and information on EGFR mutation testing and treatment was obtained from chart review. We evaluated the prevalence of EGFR mutation testing in this population and outcomes based on EGFR mutation status. Disease free survival (DFS) and clinico-pathologic characteristics were evaluated. We estimated the number of patients that would have been eligible for EGFR testing and adjuvant osimertinib therapy in the pre-ADAURA era in our patient cohort. Results: A total of 120 patients had resected stage IB-IIIA adenocarcinoma during this five-year period (Stage IB 42.5%; Stage IIA 13.3%; Stage IIB 25%; Stage IIIA 19.2%) with a median age of 66 years. Most were females (59%), NHWs (51.5%), Hispanics (46.9%), and former smokers (66.7%). Out of patients with Stage IB-IIIA NSCLC with adenocarcinoma, 42.5% completed recommended adjuvant platinum-based chemotherapy. Only 40% of patients were referred for EGFR testing during this study period. The prevalence of EGFR mutations in this population was 10.8% (13 /120), but 59% of cases had no available EGFR testing. The most prevalent mutation was L858R (53.8%) followed by exon-19 deletions (30.8%). A total of 6 patients received an EGFR TKI therapy during the follow up period (2 in the adjuvant setting). With a median follow up of 12 mos, the rate of recurrence by stage was: Stage IB (3.9%); Stage IIB (10%); Stage IIIA (13%). Median time to disease progression or death was 13 months in this subgroup. There was no difference in disease free survival for patients with EGFR testing and those without results available in this short follow up period. Conclusions: Based on this retrospective review, up to 60% of patients with early-stage NSCLC with non-squamous histology have no available EGFR testing in the pre-ADAURA era. Of the anticipated 20% of patients with expected EGFR mutations based on historical controls, we have only identified half of patients that would have been eligible for adjuvant osimertinib. This study establishes the importance of upfront EGFR mutation testing in all NSCLC patients, not only to prognosticate, but also to identify the subset of patients who could benefit from adjuvant EGFR therapy.

e19538 Background: A major unmet clinical need in the care of early-stage MF patients is the identification of those with a high risk of failing skin directed therapy or progressing to advanced disease. Herein, we inquired if the identification of a clonal T-cell receptor (TCR) gene rearrangement by PCR in peripheral blood could predict the clinical outcome, particularly the need for systemic treatment, in patients with stage IB MF. Methods: This is a retrospective cohort study of patients with stage IB MF who underwent peripheral blood TCR clonality analysis by PCR. The primary outcome of the study was time from diagnosis to initiation of systemic treatment. Secondary outcomes were: (1) time to progression to advanced-stage disease (stages IIB-IV) and (2) overall survival. Patients were censored at time of last clinical follow up. Log rank test was used to compare the survival distributions of the two groups; p value < 0.05 was considered significant. Results: From May 2014 to October 2019, 56 consecutive stage IB pts with > 6 months follow up were included in this analysis. Peripheral blood TCR clonality status was available in 42 patients: 18 pts had a positive TCR clone and 24 did not. Median follow up time was 36 months (range 8.5 – 198 months). At 3 years, 39% of patients with peripheral clone had progressed to systemic treatment versus 8% of those without a peripheral clone (log rank test, p-value = 0.003). For the secondary outcomes, at 3 years 17% of patients with peripheral clone had progressed to advanced stage versus 4% of those without (log rank test, p-value = 0.10); 5% of patients with peripheral clone had died versus 0% of those without (log rank test, p-value = 0.03). Conclusions: Detection of a predominant TCR clone by PCR in the peripheral blood is an important prognostic marker in the initial workup of MF, as its presence is highly correlated with subsequent progression to systemic treatment and death. If this finding is validated, it can be used to risk stratify and individualize therapy for MF patients.[Table: see text]
