Port-site recurrence following laparoscopic para-aortic lymphadenectomy for squamous carcinoma of the cervix

Port-site metastasis following robotic-assisted radical hysterectomy for squamous cell cervical cancer

► Port-site metastases can occur following treatment for cervical cancer. ► Port-site metastases can occur following robotic assisted laparoscopic surgery. ► The pathogenesis of port-site metastases is poorly understood.

Regenerative therapy after cancer: what are the risks?

There is often a pressing need for reconstruction after cancer surgery. Regenerative therapy holds the promise of more natural and esthetic functional tissue. In the case of breast reconstruction postmastectomy, volume retention problems associated with autologous fat transfer could be ameliorated by augmentation with cells capable mediating rapid vascularization of the graft. Intentional placement of regenerating tissue at the site of tumor resection raises questions concerning the possibility of promoting cancer recurrence. Here we review coculture and animal models of tumor/mesenchymal stem cell interactions under regenerating conditions. Available evidence from case reports, cell lines, and clinical isolates favors the interpretation that regenerating tissue promotes the growth of active, high-grade tumor. In contrast, dormant cancer cells do not appear to be activated by the complex signals accompanying wound healing and tissue regeneration, suggesting that engineered tissue reconstruction should be deferred until cancer remission has been firmly established.

Port-site and liver metastases after laparoscopic pelvic and para-aortic lymph node dissection for surgical staging of locally advanced cervical cancer

Recently, we experienced a case of port-site and liver metastases after 75 cases of laparoscopic transperitoneal pelvic lymph node dissection (PLND) and para-aortic lymph node dissection (PALND) for surgical staging of locally advanced cervical cancer. A 45-year-old-woman with stage IIB cervical adenocarcinoma underwent laparoscopic PLND and PALND for surgical staging. There was no intraperitoneal disease and cervical tumor was not manipulated at the time of laparoscopic surgery. Pathologic examination revealed only one micrometastasis in left internal iliac lymph node (LN), measuring 1 mm, of the 60 pelvic and para-aortic LNs removed. She received concurrent chemoradiation therapy and pelvic mass disappeared completely. One month after the completion of therapy, both lateral and umbilical port-site and liver metastases were detected. We conclude that although cases of port-site metastasis have mostly occurred after extensive disease, the possibility of such complication should be kept in mind at laparoscopy of early cancer and laparoscopy which does not manipulate primary tumor.

Peritoneal carcinomatosis after laparoscopic radical hysterectomy for early-stage cervical adenocarcinoma

BACKGROUND

The risk of wound metastasis after laparoscopic management of early-stage cervical cancer is well known, but there are few data on peritoneal carcinomatosis of cervical adenocarcinoma.

CASE

We report the first case of peritoneal carcinomatosis occurring in a woman with FIGO stage Ib1 cervical adenocarcinoma who underwent laparoscopic type III radical hysterectomy and bilateral pelvic lymphadenectomy (sentinel node procedure) followed by vaginal brachytherapy. A peritoneal recurrence was diagnosed 16 months after surgery and was treated with chemotherapy and laparotomy.

CONCLUSION

Laparoscopy for cervical adenocarcinoma may carry a risk of peritoneal dissemination.
