RESUMEN
Peritoneal cancer is the invasion by malignant cells of serous membrane that lines the abdominal cavity, the viscera, and the coelom of the amniotes. Histologically, it is indistinguishable from ovarian counterpart, although in the former, it commonly involves the ovary only superficially, or it may totally lack an ovarian component, but with extensive involvement of the peritoneum, calcified perihepatic peritoneal nodules, or involvement of the omentum, in most cases. The current study describes the case of a 54-year-old female patient referring a history of colitis and dairy intolerance. A transvaginal ultrasound and a computed tomography (CT) scan revealed a tumor measuring 70 × 61 × 63 mm. CA-125 serum levels were 880 U/ml. Laparotomy surgery was indicated, and tumor was found at the level of the rectovaginal septum without evidence of metastasis. Tumor dissection and protective colostomy with loop sigmoid colon were performed. A pathological study gave a diagnosis of a high-grade peritoneal serous carcinoma with a micropapillary pattern. The present study describes the case of papillary serous peritoneal cancer presented as a single tumor mass without extensive involvement of the peritoneum. Additionally, the need for routine tests for its diagnosis and documenting hormonal alterations as the cause of its origin are suggested.
RESUMEN
PURPOSE: The impact of disease activity or treatments on health-related quality of life (HRQL) is crucial in Oncology, but adequate instruments for this assessment are scarce. Our aim is to validate the Mexican-Spanish version of the QLQ-EN24 questionnaire to evaluate HRQL in women with endometrial cancer (EC). METHODS: This is a prospective study of Mexican women with EC, attending a single cancer centre, who responded the QLQ-C30 and QLQ-EN24 instruments; usual psychometric analysis were performed as well as the association of HRQL scales and relevant clinical data. Correlation analysis was performed with the Spearman's method, reliability analysis with the Cronbach's alpha, known-group comparisons with the Kruskal-Wallis test, and survival analysis with the Kaplan-Meier method and Log-rank test. RESULTS: One hundred and eighty-nine women with EC were assessed. Most functional scales reported high values, and most symptom scales, low. Questionnaire compliance rates were high and internal consistency tests demonstrated adequate convergent and divergent validity. Cronbach's α coefficients of the five multi-item scales the QLQ-EN24 instruments were from 0.659 to 0.887. Scales of the QLQ-C30 and QLQ-EN24 instruments distinguished among clinically distinct groups of patients, particularly based on serum albumin levels. The Urological symptoms, Gastrointestinal symptoms, Body image, Pelvic pain and Taste change scales were significantly associated with OS. CONCLUSION: The Mexican-Spanish version of the QLQ-EN24 questionnaire is reliable and valid for the assessment of HRQL in patients with EC and can be broadly used in multi-national clinical trials. However, conclusions derived from scales evaluating sexual function should be handled carefully.
