Thrombocytosis as a predictor of distant recurrence in patients with rectal cancer.

Background And Aims: Thrombocytosis is frequently observed in patients with malignancy. We undertook this study to determine the prognostic value of thrombocytosis in patients with rectal cancer.

Methods: We performed a retrospective study of patients undergoing low anterior resection for rectal cancer between January 2000 and March 2007.

[Breast cancer in Mexican women under 40].

Background: Breast cancer is the leading cause of death from malignancy in women. The incidence increases with age, but the relationship between age and survival of breast cancer patients is not well defined. It is observed that young women with breast cancer have patterns more aggressive biological.

[Laparoscopic radical hysterectomy with lymphatic mapping and sentinel lymph node biopsy in early cervical cancer].

Background: in patients with early-stage cervical cancer (FIGO IA, IB2 and IIA), the incidence of lymph node metastases is up to 15%; the majority of early cervical cancer patients with pelvic and para-aortic lymphadenectomy does not benefit with the procedure and are at risk of associated morbidity (linfocyst, lymphedema, vascular or nerve damage).

Objective: To describe the experience and usefulness of lymphatic mapping and sentinel lymph node with total laparoscopic radical hysterectomy in early stage cervical cancer.

Patients And Method: Retrospective study in patients with diagnosis of cervical cancer in early stage, submitted to laparoscopic radical hysterectomy with lymphatic mapping and sentinel lymph node biopsy.

[Laparoscopy for staging and treatment of cervical cancer].

Background: Laparoscopic surgery for cervical cancer (CC) study and treatment is one of the main achievements in last years.

Objective: Describe the feasibility and experience of laparoscopic procedures for CC staging and treatment.

Patients And Method: A retrospective analysis of 75 patients with CC in different stages was done, group I included CC in situ patients treated with type I Piver hysterectomy, in group 2, patients with early CC treated with type II or III radical hysterectomy with pelvic lymphadenectomy and para-aortic lymph node sampling, and group 3 patients with locally advanced CC submitted to pelvic and para-aortic lymphadenectomy.

Prognostic significance of circumferential margin involvement in rectal adenocarcinoma treated with preoperative chemoradiotherapy and low anterior resection.

Introduction: Histologic examination of circumferential margins is an important predictor of local and distant relapse in non-radiated rectal cancer. However, for patients who received preoperative chemoradiotherapy this role has not yet been addressed.

Methods: From January 1995 to December 1997, 61 patients with rectal adenocarcinoma located between 0 and 10 cm from anal verge with invasion into perirectal fat assessed by rectal ultrasound were included.

[Transverse glossectomy for tongue cancer treatment].

Introduction: Standard care of patients with oral tongue-invasive squamous cell carcinoma in early stages is local resection and neck dissection. Traditionally, tumor resection was performed with hemiglossectomy (tongue resection in lingual long axis), which implied morbidity for deglutition and speech. Although surgical margins are sufficient, they are usually larger than necessary.
