RESUMEN
Small bowel adenocarcinoma (SBA) is an extremely rare cancer type. In the present study, the patient characteristics and clinical outcomes of patients diagnosed and treated for SBA at a single tertiary hospital were reported. All patients diagnosed and managed between 2007 and 2020 were reviewed. Regression analysis was used to assess variables associated with the metastatic stage at diagnosis. The Kaplan-Meier method was used to estimate survival and the log-rank test was used to determine factors associated with survival outcomes. Out of 137 cases of small bowel primary tumor, 43 consecutive patients with SBA were diagnosed with a median age of 53 years and the majority (76.7%) were males. The common initial presenting symptoms were abdominal pain (58.8%) and bowel obstruction (30.2%). The most common primary site was the duodenum (60.5%) and the majority (65.1%) were diagnosed with stage III/IV disease. Patients with a high neutrophil-lymphocyte ratio (NLR) (≥0.85) were more likely to be in the metastatic stage at diagnosis (P=0.01). The 3-year overall survival (OS) rates based on stage were 100% (I), 85% (II), 53% (III) and 33.9% (IV) (P=0.001). In addition to the stage, the Eastern Cooperative Oncology Group Performance Status (P<0.001), NLR (P<0.001), hypoalbuminemia (P=0.02) and chemotherapy in a metastatic setting (P=0.02) were prognostic factors for OS. In conclusion, NLR is a potential prognostic biomarker for a metastatic stage at diagnosis. Advanced stage, lower performance status score, low albumin level and high NLR are associated with short OS.
RESUMEN
OBJECTIVES: Ovarian granulosa cell tumour is rare. This study aims to report the clinical characteristics and long-term outcomes of adult-type ovarian granulosa cell tumour (AOGCT) at King Faisal Specialist Hospital and Research Centre (KFSH&RC) and to determine the prognostic factors affecting relapse and survival. METHODS: We retrospectively reviewed patients with AOGCT, from 1988 to 2014, who were treated at our institution. Baseline characteristics, pathological findings, and outcomes were analysed and reported. RESULTS: Sixty-one patients with AOGCT were identified with a median age of 49 years. Median follow-up was 5.0 years (range 2.1-8.2 years). 74% of patients were FIGO (International Federation of Gynecology and Obstetrics) stage I, whereas 7% were stage II, 5% were stage III, and unknown in 14% of the cases. The most common presenting symptoms included abdominal pain (43%) and vaginal bleeding (43%). The majority of patients (38 patients, 62%) were treated with total abdominal hysterectomy and bilateral salpingo-oophorectomy. Five (8%) patients received adjuvant chemotherapy. Sixteen patients (26%) relapsed with a median time to relapse of 5.5 years (0.7-8.1 years). Half of the recurrences (eight patients, 50%) occurred after five years of diagnosis. Five-year overall survival and disease-free survival (DFS) were 93% and 84%, respectively. Factors associated with a high risk of recurrence were the presence of ascites (p=0.000) and elevated preoperative CA 125 level (p=0.048). The overall survival was significantly influenced by the menopausal status (premenopausal 100% vs. postmenopausal 84%; p=0.02), preoperative CA 125 (normal 100% vs. elevated 64%; p=0.005), ascites (present 33% vs. absent 100%; p=0.000), and age (<55 years 100% vs. ≥ 55 years 77%; p= 0.002). CONCLUSION: This study confirms a good outcome for patients with AOGCT. They require long-term follow-up as late recurrences can occur many years post definitive therapy. The presence of ascites and elevated preoperative CA 125 levels were associated with a higher risk of recurrence and poor prognosis. Outcomes appear unaffected by fertility-sparing surgery or adjuvant chemotherapy.
