A Comprehensive Discussion in Vaginal Cancer Based on Mechanisms, Treatments, Risk Factors and Prevention

Vaginal cancer is a rare and uncommon disease that is rarely discussed. Although vaginal cancer traditionally occurs in older postmenopausal women, the incidence of high-risk human papillomavirus (HPV)-induced cancers is increasing in younger women. Cervical cancer cells contain high-risk human papillomavirus (HPV) E6 and E7 proteins and inhibiting HPV gene expression leads the cells to stop proliferating and enter senescence. As E6, and E7 protein promoted the carcinogenesis mechanism, and here not only regulate the cellular degradation of P53, and pRb but also enhances the cell proliferation along with E6 protein targets the p53 for breakdown and subsequently promote the apoptotic cell death, and DNA repair inhibition, that is indispensable to the continue the lifecycle of the HPV. As a synchronous or metachronous tumor, vaginal cancer is frequently found in combination with cervical cancer. It is uncertain what causes invasive female vaginal organ cancer. HPV type 16 is the most often isolated HPV type in female vaginal organ cancers. Due to cancer's rarity, case studies have provided the majority of etiologic findings. Many findings demonstrate that ring pessaries, chronic vaginitis, sexual behavior, birth trauma, obesity, vaginal chemical exposure, and viruses are all risk factors. Because of insufficient understanding and disease findings, we are trying to find the disease's mechanism with the available data. We also address different risk factors, therapy at various stages, diagnosis, and management of vaginal cancer in this review.

Innovations in the Management of Vaginal Cancer

Primary vaginal cancer is a rare gynecologic malignancy. Given the rarity of the disease, standardized approaches to management are limited, and a great variety of therapeutic conditions are endorsed. This paper reviews advances in surgical approaches, radiation, chemoradiation, and immunotherapy. Advances in surgical management including the increasing use of laparoscopic and endoscopic approaches, as well as the novel techniques in vaginal reconstruction, are reviewed. Concurrent chemoradiation remains a mainstay of treatment for vaginal cancer and has improved local control of disease and overall survival. Additionally, with metastatic disease or situations where toxicity from CCRT is unacceptable, systemic therapies including immunotherapy approaches are reviewed.

The Versatility of the Fasciocutaneous Infragluteal (FCI) Flaps for locoregional or free flap reconstruction

BACKGROUND

The wide range of reconstructive purposes requires specific demands and considerations for appropriate flap selection. One versatile and reliable option, which is rarely reported in current literature, is the fasciocutaneous infragluteal (FCI) flap. In this study, we present our results of performing the FCI flap for different clinical indications.

PATIENTS AND METHODS

This retrospectively study was conducted between September 2011 and September 2019. We included 30 patients (21 females and 9 males) who underwent reconstruction with either pedicled or free FCI flap. Indications for performing FCI flap were uni- or bilateral autologous breast reconstruction, perineal reconstruction, congenital thoracic deformity, lower extremity coverage, and vulva reconstruction.

RESULTS

Forty-one FCI flaps were performed (34 free and 7 pedicled flaps). The average flap dimension was 7  ×  20 cm (range, 7-8  ×  19-21) and the mean length of the pedicle was 13.4 cm (range, 10.5-15.5). The mean diameter of the artery was 2.5 mm (range, 2.2-3.2), the mean diameter of the accompanying vein was 3 mm (range, 2.4-3.3). The flap survival rate was 97.6% (one flap loss). The most common minor complications were infragluteal wound healing disorders and hematoma.

CONCLUSION

The FCI flap provides constant and reliable anatomy with a long vascular pedicle as well as enough soft tissue bulk and a well-hidden scar. In our clinical practice, this flap has emerged as a first choice in perineal/vulvar reconstruction and a reliable alternative in breast reconstruction if the gold standard procedure cannot be performed.

Redefining the Reconstructive Ladder in Vulvoperineal Reconstruction: The Role of Pedicled Perforator Flaps

BACKGROUND

 Gynecological reconstruction is difficult, particularly in cases with recurrence and received previous surgeries and/or radiotherapy and necessitate secondary reconstruction. Perforator flaps can preserve other donor sites for potential later reconstruction, and they also can be better tailored to the defect. We hypothesized that the use of perforator-based flaps can better restore the defect with less complications.

METHODS

 A retrospective review was conducted of all patients who underwent vulvar-perineum reconstruction between 2011 and 2018 by the senior author, and oncologic and reconstructive outcomes and complications were analyzed.

RESULTS

 Thirty-three patients underwent 55 soft tissue reconstructions for vulvar-perineum defects during the study period. The mean follow-up time was 27.6 ± 28.9 months. Squamous cell carcinoma was the most common cancer (45.5%). For 11 patients (33.3%), the procedures were performed for the treatment of recurrent cancer. The average defect size was 39.8 ± 34.3 cm². The overall survival rate was 90.3%. Profunda artery perforator flaps were the most commonly applied flap for reconstruction in both the primary and recurrent groups. Poor wound healing was the most common complication which occurred in 10 of the 55 flaps (18.2%). Perforator flaps presented fewer complications than myocutaneous flaps or traditional random flaps. Similarly, Island pedicle flap design also presented fewer complications than traditional rotation flaps. With proper reconstruction, previous surgery or radiotherapy did not contribute to an increase in complications.

CONCLUSION

 In our experience, perforator flaps can provide satisfactory reconstruction for perineum reconstruction with low postoperative complications while preserving other donor sites in the event of disease recurrence for repeat resection and reconstruction. Previous surgery or radiotherapy did not increase the complications or preclude its usage. A redefined reconstructive ladder was created to help selecting the best state-of-the-art technique for reconstruction to achieve better results.

Experience with gluteal V-Y fasciocutaneous advancement flaps in vulvar reconstruction after oncological resection and a modification to the marking: Playing with tension lines

Many post-vulvectomy vulvar reconstruction solutions, using local fasciocutaneous flaps where possible, have been proposed. We report the use of V-Y advancement flaps from the gluteal fold in medium to large vulvar reconstructions and a simple modification we made to the technique in order to minimise wound-related complications. Between 2006 and 2016, 30 vulvar reconstructions were performed via a total of 59 flaps, 24 of which were raised using the proposed modification to the plasty design. Short- and long-term (24 months) follow-up data were analysed, postoperative flap sensitivity was tested, and any arising complications were recorded. The mean age of patients treated was 75.3 years (51-92 years). The mean monolateral defect dimensions were 7.5 × 4.7 × 2.8 cm. Minor complications were recorded in 23% of patients (14% of flaps). One case of ostial stenosis occurred. Micturition and ambulation recovery was rapid, and flap sensitivity was fully restored 24 months after reconstruction. Scars were well hidden by natural soft tissue folds. The outcomes in this case series confirm that the gluteal V-Y advancement fasciocutaneous flap is a useful and simple technique for reconstructing even large vulvar defects. It has a low functional and aesthetic impact and enables rapid return to autonomy. Moreover, the simple modification to the V-Y flap proposed, designed to reduce tension at the apical part of the wound, appears to reduce the complication rate.

Reconstruction of the Vulva with Sensate Gluteal Fold Flaps

Backround and Aims: Soft-tissue reconstruction of the vulva following resection of malignancies is challenging. The function of perineal organs should be preserved and the reconstructed area should maintain an acceptable cosmetic appearance. Reconstruction with local flaps is usually sufficient in the primary phase after a radical vulvectomy. Numerous flaps have been designed for vulvar reconstruction usually based on circulation from the internal pudendal artery branches.

In this paper we introduce our modification of the gluteal fold V–Y advancement flap as a primary reconstruction after a radical vulvectomy.

Patients and Methods: Twenty-two patients were operated with a radical vulvectomy because of vulvar malignancies. The operation was primary in eight and secondary in 14 patients. The reconstruction of the vulva was performed in the same operation for each patient

Results: All flaps survived completely. Wound complications were registered in three patients. Late problems with urinary stream were corrected in two patients. A local recurrence of the malignancy was observed in six patients during the follow-up period.

Conclusions: Gluteal fold flap is easy to perform, has a low rate of complications and gives good functional results.

Even a large defect can be reconstructed reliably with this method. A gluteal fold V–Y advancement flap is sensate and our modification allows the flap to be transposed with lesser dissection as presented before.
