Role of hyperthermic intraperitoneal chemotherapy in ovarian cancer.

Epithelial ovarian cancer (EOC), has the highest worldwide mortality of all gynecological tumors, in 75% of cases is diagnosed in advanced stages. Despite of treatments with maximal cytoreductive surgery (CRS) and platinum-based chemotherapy (CT), approximately 70% of patients with advancedstage disease relapse within 18 months, given this high number of recurrences, new approaches are needed to improve outcomes for these patients. Hyperthermic intraperitoneal chemotherapy (HIPEC) has fundamentally changed the treatment of patients with ovarian cancer, with complete CRS and locoregional administration of chemotherapy. The purpose of this review is to find the most relevant, reliable published evidence of the use of HIPEC in ovarian cancer, together with an overview of peritoneal carcinomatosis (PC), procedures, therapeutic approaches in first-line and recurrent disease, the benefit of hyperthermia, selection of the ideal patient for the HIPEC procedures as well to analyze the disease free survival (DFS), morbidity, mortality and overall survival (OS) in patients with ovary cancer. So far, the small amount of evidence points favorably to the use of CRS and HIPEC as a first line of therapy, but more prospective randomized trials are needed to officially adopt this procedure as a standard of care, additionally patients need to know this option exists.

[Open splenectomy: ten-year experience in an oncological referral center]. / Esplenectomía a cielo abierto. Experiencia de 10 años en un centro oncológico.

BACKGROUND: Open splenectomy is a useful procedure for some diseases with splenomegaly >1500 g. We undertook this study to evaluate open splenectomy morbidity and mortality at the Instituto Nacional de Cancerologia in Mexico City. METHODS: We reviewed the clinical files of patients with benign and malignant hematological diseases, as well as other diseases, who underwent splenectomy from 1994 to 2005. RESULTS: Twenty five patients with a mean age of 38.5 years were submitted for open splenectomy. Splenomegaly was found in 12 patients (48%). The most frequent abdominal wall incision was transverse left subcostal (64%). Average surgical time was 125 min, bleeding 485 ml, spleen weight 1553.6 g and mean size 15 x 11 x 12 cm. Mean hospital stay was 7.5 days. Eighteen patients (72%) did not have immediate complications. One patient (4%) developed surgical wound infection, two patients (8%) had significant pain, three patients (12%) had bleeding and one patient (4%) developed intraabdominal fluid collection. Twenty one patients (84%) did not have further complications. One patient (4%) developed multiple organ failure, another patient (4%) developed thrombocytopenia and another (4%) developed severe pain. During an average 81-month follow-up we found 14 patients (56%) asymptomatic, two patients (8%) with documented tumoral activity (angiosarcoma and non-Hodgkin's lymphoma) and one patient (4%) developed a second neoplasm. Six patients (24%) died due to underlying disease (chronic myeloid leukemia and lymphoma), one patient (4%) with active disease (Hodgkin's disease) and one patient (4%) died due to other causes. CONCLUSIONS: With a spleen >1500 g, open surgery offers better visibility and, in fact, less morbidity and mortality.

Adjusted carbohydrate antigen 19-9. Correlation with histological grade in pancreatic adenocarcinoma.

BACKGROUND: The serum level of carbohydrate antigen 19-9 (CA 19-9) depends on the tumor size and differentiation grade. Jaundice can cause an elevation of serum CA 19-9, although the nature of this interaction is not fully understood. PATIENTS AND METHODS: This was a retrospective study of 26 patients with potentially resectable pancreatic adenocarcinoma. Serum CA 19-9 was correlated with the histological differentiation. CA 19-9 adjusted for serum bilirubin was determined and analyzed. RESULTS: No correlation between CA 19-9 and histological differentiation was determined (p>0.05). The median adjusted CA 19-9 level was significantly lower (p=0.01) in patients with normal biliary excretion than those with bilirubin levels >2 mg/dL. CONCLUSION: These data are consonant with the theory of a dual contribution to the serum CA 19-9 level from biliary obstruction and tumor cell synthesis.

[Maffucci's syndrome. Case reports and literature review]. / Síndrome de Maffucci. Informe de dos pacientes y revisión de la literatura.

Maffucci syndrome is a rare, congenital disease, which is associated with the appearance of multiple enchondromas (possibility of malignant transformation in 20 to 100%), soft tissue hemangiomas and other mesenchymatous injuries. Case 1 is a 33-year-old female who presented with multiple nodules predominantly in upper extremities. Upon examination, there was deformity in articulation and nodules on the hands, which were soft and moveable. There were bony shavings in the second and fourth fingers of the left hand (enchondromas and atypical cells associated with hemangioma esclerosante). Maffucci syndrome was diagnosed. Later, excision of subcutaneous nodules in superior extremities was performed along with excision of nodules in both hands and hypochondrium (enchondroma injuries of left hand and hypochondrium, hemangioma in right hand). There was dysarticulation of the second finger at the metacarpal level of the phalanges of the left hand (chondrosarcoma). The patient is being followed up currently. Case 2 is a 26-year-old female. The patient had a history of subcutaneous abdominal tumor, exostosis, nodules and nodule in right breast. Upon examination, a tumor was found in the right breast, exostosis of right tibia, injury to the right wrist and left thyroid nodule. A simple mastectomy and axillary dissection was performed (fibroadenoma to intracanalicular and 14 negative lymph nodes). Later, left thyroidectomy and lumpectomy in right wrist were performed (hyperplasia to nodular thyroid and hemangioma cavernous). There was injury in the carpus of the right hand and elbow (hemangioma cavernous and synovial tissue with fibrosis and enchondroma). A diagnosis was made of Marffucci syndrome associated with mesenchymatous tumors. The patient was in poor general health and did not survive this hospitalization.

Angiomiolipoma de hígado no asociado a esclerosis tuberosa / Liver angiomyolipoma non associated to tuberous sclerosis

El angiomiolipoma es un tumor benigno del hígado poco frecuente. Se presenta el caso de una paciente de 32 años de edad, a quien se le realizó ultrasonido abdominal por sospecha de embarazo, detectándose masa hiperecoica en el lóbulo izquierdo del hígado, misma que se corroboró por tomografía. La biopsia percutánea reportó neoplasia maligna compatible con liposarcoma, por lo que se decidió realizar laparotomía exploradora, efectuando resección hepática, que evolucionó sin complicaciones. El informe anatomopatológico fue de angiomiolipoma de hígado. Este caso demuestra la dificultad para realizar el diangóstico preoperatorio de lesiones grasas en hígado, por lo que se revisó la literatura y se discutió el diagnóstico, así como el tratamiento de estas lesiones
