"Long-term oncologic outcomes and risk factors for distant recurrence after pathologic complete response following neoadjuvant treatment for locally advanced rectal cancer. A nationwide, multicentre study".

BACKGROUND: Pathologic complete response (pCR) after multimodal treatment for locally advanced rectal cancer (LARC) is used as surrogate marker of success as it is assumed to correlate with improved oncologic outcome. However, long-term oncologic data are scarce. METHODS: This retrospective, multicentre study updated the oncologic follow-up of prospectively collected data from the Spanish Rectal Cancer Project database. pCR was described as no evidence of tumour cells in the specimen. Endpoints were distant metastases-free survival (DMFS) and overall survival (OS). Multivariate regression analyses were run to identify factors associated with survival. RESULTS: Overall, 32 different hospitals were involved, providing data on 815 patients with pCR. At a median follow-up of 73.4 (IQR 57.7-99.5) months, distant metastases occurred in 6.4% of patients. Abdominoperineal excision (APE) (HR 2.2, 95%CI 1.2-4.1, p = 0.008) and elevated CEA levels (HR = 1.9, 95% CI 1.0-3.7, p = 0.049) were independent risk factors for distant recurrence. Age (years) (HR 1.1; 95%-CI 1.05-41.09; p < 0.001) and ASA III-IV (HR = 2.0; 95%-CI 1.4-2.9; p < 0.001), were the only factors associated with OS. The estimated 12, 36 and 60-months DMFS rates were 96.9%, 91.3%, and 86.8%. The estimated 12, 36 and 60-months OS rates were 99.1%, 94.9% and 89.3%. CONCLUSIONS: The incidence of metachronous distant metastases is low after pCR, with high rates of both DMFS and OS. The oncologic prognosis in LARC patients that achieve pCR after neoadjuvant chemo-radiotherapy is excellent in the long term.

Cáncer de recto localmente avanzado. La necesidad de la superespecialización / Locally advanced rectal cancer. The need for further specialization

Presentamos un caso que por sus connotaciones diagnósticas y terapéuticas resulta especialmente didáctico e ilustrativo, pues aborda el cómo, el quién y dónde debe realizarse la cirugía de cáncer de recto localmente avanzado. Ilustra el manejo diagnóstico y la estadificación del cáncer de recto en el momento actual. Este caso se aborda en el comité de forma multidisciplinar, y reúne los distintos avances en la cirugía de cáncer de recto de los últimos años (escisión total mesorrectal, abordaje laparoscópico, radioterapia intraoperatoria, resección perineal extendida, reparación del suelo pélvico con material protésico). Todo ello aunado a la opinión de que deben ser instituciones y grupos muy especializados y dedicados al tratamiento de esta patología los que deberían centralizar su atención médica.

We present a case, which due to its diagnostic and therapeutic connotations makes it especially educational, as it addresses the how, the who and where should the surgery be performed for locally advanced rectal cancer. It illustrates the diagnostic management and staging of rectal cancer at the present time. The case is approached in a multidisciplinary committee manner, and binds the various advances in surgery of rectal cancer in recent years (total meso-rectal excision, laparoscopy, intraoperative radiotherapy, extended perineal resection, pelvic floor repair with prosthetic material). This serves to underline the view that there must be highly specialized institutions and groups dedicated to the treatment of this condition in order to centralize its health care.

[Laparoscopic adrenalectomy: presentation of 43 cases]. / Adrenalectomía laparoscópica: presentación de 43 casos.

INTRODUCTION: The aim of the study was to present and analyse our experience in laparoscopic adrenalectomy (LA). MATERIALS AND METHODS: Descriptive and retrospective study including LA performed over 8 years, between 2000 and 2008 in our hospital. RESULTS: A total of 43 LA were performed to 41 patients using a transperitoneal lateral approach. Indications for adrenalectomy included hyperaldosteronism (19), non-functioning adenoma (8), phaeochromocytoma (6), Cushing's syndrome (6), metastasis (3) and adrenal primary tumour (1). Median postoperative hospital stay was 3 days and the median size of the masses was 30mm (range: 4-155mm) Complications occurred in 3 patients (2 respiratory infections, and 1 intraoperative bleeding). There was no mortality. Only one case needed conversion to open adrenalectomy; no patients required reintervention. CONCLUSION: Laparoscopic adrenalectomy is a safe and effective method in the treatment of adrenal masses and it can be performed with minimal risk and morbidity.
