RESUMO
Peritoneal carcinomatosis (PC) has been traditionally considered a terminal disease with median survivals reported in the literature of 6 to 12 months. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) are playing an ever increasing role in the treatment of these patients. Excellent results have been achieved in well-selected patients but there is a very steep learning curve when starting a new program. A program for peritoneal surface malignancies in which patients with PC of gastrointestinal or gynecological origin were treated using multimodality therapy with combinations of systemic therapy, cytoreductive surgery (CRS), and HIPEC was initiated in December 2007 at "Hospital Regional de Alta Especialidad de Oaxaca," Mexico. We present the results of our initial experience. From December 2007 to February 2011, 26 patients were treated with CRS and HIPEC. There were 21 female patients. Most common indication (46%) was recurrent ovarian cancer. Mean duration of surgery was 260 minutes. Mean Peritoneal Cancer Index was 9. Twenty-three (88.5%) patients had a complete cytoreduction. Major morbidity and mortality rates were 19.5 and 3.8 per cent, respectively. Mean hospital stay was 8 days. At a mean follow-up of 20 months, median survival has not been reached. Rigorous preoperative workup, strict selection criteria, and mentoring from an experienced cytoreductive surgeon are mandatory and extremely important when starting a center for PC.

Objetivo: Evaluar la hipocalcemia y lesión del nervio laríngeo recurrente secundaria a tiroidectomía total acompañada de disección del compartimiento central en cáncer papilar de tiroides. Sede: Instituto Nacional de Cancerología, México. Diseño: Estudio clínico descriptivo, observacional, prospectivo, longitudinal. Análisis estadístico: Porcentajes como medida de resumen para variables cualitativas. Pacientes y métodos: Veinte y cuatro pacientes con diagnóstico de cáncer papilar de tiroides (CPT) establecido mediante citología y/o histopatología, que se llevaron a disección central del cuello como parte del tratamiento quirúrgico inicial con seguimiento mínimo de 6 meses. Variables estudiadas: Tiempo quirúrgico, sangrado transoperatorio, movilidad cordal evaluadas por laringoscopia directa pre y postoperatoriamente, hipocalcemia e hipoparatiroidismo, reintervención y número de ganglios resecados. Resultados: De los 24 pacientes, 16 con enfermedad confinada al tiroides y 8 con afección al cuello, el tiempo quirúrgico medio de 2 a 4.30 horas con una media de 2.2, sangrado de 100 a 400 ml con media de 196 ml. Un paciente con hipocalcemia transitoria, cero pacientes con hipocalcemia permanente corroborado con paratohormona, cero lesiones del nervio laríngeo recurrente (NLRL), cero reintervenciones, el número de ganglios resecados fue de 7 a 16. Conclusiones: La morbilidad de la tiroidectomía total más disección del compartimiento central fue de hipocalcemia transitoria de 4.1%. No existió lesión de nervio laríngeo recurrente ni hipoparatiroidismo.
Objective: To assess hypocalcemia and injury to the recurrent laryngeal nerve secondary to total thyroidectomy plus central compartment dissection in papillary thyroid cancer. Setting: National Institute of Cancerology, Mexico Design: Descriptive, observational, retrospective, prospective, longitudinal clinical study. Statistical analysis: Percentages as summary measure for qualitative variables. Patients and methods: Twenty-four patients with diagnosis of papillary thyroid cancer (PTC), established by cytology and histopathology, subjected to central dissection of the neck as part of the initial surgical treatment with a follow-up of at least 6 months. Assessed variables were: surgical time, trans-operative bleeding, vocal cords mobility, assessed through direct laryngoscopy pre- and postoperatively, hypocalcemia and hypothyroidism, re-intervention, and number of dissected ganglia. Results: Twenty four patients, 16 with thyroid-confined disease, and 8 with neck involvement. Average surgical time of 2 to 4.30 hours, mean of 2.2, bleeding of 100 to 400 ml, mean of 196 ml. One patient with transient hypocalcemia, nill patients with permanent hypocalcemia confirmed with PHT testing, nill Recurrent laryngeal nerve (NLRL) injuries, nill re-interventions; the number of dissected ganglia was 7 to 16. Conclusions: Morbidity of total thyroidectomy plus dissection of the central compartment consisted of transient hypocalcemia (4.1%). Neither recurrent laryngeal nerve injury nor hypoparathyroidism occurred.
