ABSTRACT
A 51-year-old woman received a laparoscopic surgical staging operation due to endometrial carcinoma. Adjuvant pelvic radiotherapy was performed when the endometrial carcinoma was staged at FIGO Stage IIIC1, adnexa metastasis. Three months completing adjuvant pelvic radiotherapy, a 2.5-cm vaginal stump mass was found by abdomino-pelvic computed tomography (AP-CT). To rule out local recurrence, diagnostic laparoscopic exploration was performed. The pathologic report revealed chronic inflammation due to the presence of a foreign body. To avoid unnecessary surgery during the follow-up of patients with gynecologic malignancies, anti-adhesive material should be avoided which can possibly cause a lesion mimicking local recurrence.

Identification of antigens that provide protective immunity via prophylactic and therapeutic vaccination against Mycobacterium tuberculosis is critical for the development of subunit vaccines for tuberculosis (TB). In this study, we performed a head-to-head comparison of seven well-known TB antigens delivered by DNA vaccine, and evaluated their respective immunogenicities and protective efficacies in pre- and post-exposure mouse models. All TB antigens were designed as a chimeric fusion with Flt3-L to enhance antigen-specific T-cell immunity upon vaccination. Prophylactic vaccination with the Flt3L (F)-Mtb32 DNA vaccine elicited significant protection in both the spleen and lungs against M. tuberculosis challenge, comparable to the Bacillus Calmette-Guerin vaccine. F-Ag85A and F-Mtb32 DNA vaccines, in combination with chemotherapy, reduced the bacterial burden to undetectable levels in the lungs of all mice infected with M. tuberculosis. These data collectively indicate that the F-Mtb32 DNA vaccine confers the most efficient protective immunity that suppresses bacterial growth in the active or latent status of M. tuberculosis.
