Essential surgical skills for a gynecologic oncologist

Comparison of Outcomes in Bowel Resections by Gynecologic Oncologists Versus General Surgeons During Maximal Cytoreductive Surgery for Advanced Ovarian Cancer: Gynecologic Oncology Research Investigators Collaboration Study (GORILLA-3006)

BACKGROUND

This report describes the oncologic outcomes for patients with advanced ovarian cancer who had bowel surgery performed by gynecologic oncologists (GOs) and compares the outcomes with those for bowel surgery performed by general surgeons (GSs) during maximal cytoreductive surgery.

METHODS

Patients from six academic institutions who had FIGO stage III or IV ovarian cancer and underwent any bowel surgeries during maximal cytoreductive surgery were eligible for the study. The patients were divided into two groups according to whether bowel surgery was performed by a GO or a GS. In both groups, the GOs were mainly involved in extra bowel debulking procedures. Perioperative and survival outcomes were compared between the two groups.

RESULTS

The 761 patients in this study included 113 patients who underwent bowel surgery by a GO and 648 who had bowel surgery by a GS. No discernible differences were observed in age, American Society of Anesthesiology (ASA) score, FIGO stage, histologic type, timing of cytoreductive surgery (primary or interval debulking surgery), or complications between the two groups. The GO group exhibited a shorter operation time than the GS group. Kaplan-Meier analysis showed no survival differences between the two groups. In the Cox analysis, non-serous cell types and gross residual diseases were associated with adverse effects on overall survival. However, performance of bowel surgery by a GO did not have an impact on survival.

CONCLUSION

Performance of bowel surgery by a GO during maximal cytoreductive surgery is both feasible and safe. These results should be reflected in the training system for GOs regarding bowel surgery, and further research is needed to confirm that GOs can play a more leading role in performing extra-uterine procedures.

Training the gynecologic oncologists of the future - challenges and opportunities

Several recent advances in gynecologic cancer care have improved patient outcomes. These include national screening and vaccination programs for cervical cancer as well as neoadjuvant chemotherapy for ovarian cancer. Conversely, these advances have cumulatively reduced surgical opportunities for training creating a need to supplement existing training strategies with evidence-based adjuncts. Technologies such as virtual reality and augmented reality, if properly evaluated and validated, have transformative potential to support training. Given the changing landscape of surgical training in gynecologic oncology, we were keen to summarize the evidence underpinning current training in gynecologic oncology.In this review, we undertook a literature search of Medline, Google, Google Scholar, Embase and Scopus to gather evidence on the current state of training in gynecologic oncology and to highlight existing evidence on the best methods to teach surgical skills. Drawing from the experiences of other surgical specialties we examined the use of training adjuncts such as cadaveric dissection, animation and 3D models as well as simulation training in surgical skills acquisition. Specifically, we looked at the use of training adjuncts in gynecologic oncology training as well as the evidence behind simulation training modalities such as low fidelity box trainers, virtual and augmented reality simulation in laparoscopic training. Finally, we provided context by looking at how training curriculums varied internationally.Whereas some evidence to the reliability and validity of simulation training exists in other surgical specialties, our literature review did not find such evidence in gynecologic oncology. It is important that well conducted trials are used to ascertain the utility of simulation training modalities before integrating them into training curricula.

Radical hysterectomy case volume and cervical cancer treatment in the era of COVID-19: A multi-site analysis of National Cancer Institute-designated Comprehensive Cancer Centers

OBJECTIVE

To compare radical hysterectomy case volume, cancer stage, and biopsy-to-treatment time of invasive cervical cancer diagnosed before and after onset of the COVID-19 pandemic.

METHODS

In a multi-institution retrospective cohort study conducted at 6 large, geographically diverse National Cancer Institute-designated cancer centers, patients treated for newly diagnosed invasive cervical cancer were classified into 2 temporal cohorts based on date of first gynecologic oncology encounter: (1) Pre-Pandemic: 3/1/2018-2/28/2020; (2) Pandemic & Recovery: 4/1/2020-12/31/2021. The primary outcome was total monthly radical hysterectomy case volume. Secondary outcomes were stage at diagnosis and diagnosis-to-treatment time. Statistical analyses used chi-squared and two sample t-tests.

RESULTS

Between 3/1/2018-12/31/2021, 561 patients were diagnosed with cervical cancer. The Pre-Pandemic and Pandemic & Recovery cohorts had similar age, race, ethnicity, smoking status, and Body Mass Index (BMI). During Pandemic & Recovery, the mean monthly radical hysterectomy case volume decreased from 7[SD 2.8] to 5[SD 2.0] (p = 0.001), the proportion of patients diagnosed with Stage I disease dropped from 278/561 (49.5%) to 155/381 (40.7%), and diagnosis of stage II-IV disease increased from 281/561 (50.1%) to 224/381 (58.8%). Primary surgical management was less frequent (38.3% Pandemic & Recovery versus 46.7% Pre-Pandemic, p = 0.013) and fewer surgically-treated patients received surgery within 6 weeks of diagnosis (27.4% versus 38.9%; p = 0.025).

CONCLUSIONS

Lower radical hysterectomy case volume, a shift to higher cervical cancer stage, and delay in surgical therapy were observed across the United States following the COVID-19 outbreak. Decreased surgical volume may result from lower detection of early-stage disease or other factors.

Effect of Quality Control Program in Surgical Management of Early Cervical Cancer

BACKGROUND

Regular assessments of clinical performance in gynecologic cancer surgery is important for the safety of patients. We evaluated the effects of quality control (QC) program on the treatment pattern and clinical outcomes of early cervical cancer.

METHODS

Medical records of cervical cancer patients who received operation in our institution from January 2007 to December 2018 were retrospectively reviewed. Cases were divided into 2 groups, before and after the initiation of QC program, group 1 (2007-2013) and group 2 (2014-2018), based on the operation date. Two groups were compared in clinicopathologic variables, surgical methods, operative details, adjuvant treatments, recurrence and survival.

RESULTS

A total of 305 cervical cancer patients were included in the analysis, 210 in group 1 and 95 in group 2. In group 2, minimally invasive surgery (MIS) was more frequently performed (60.0% vs. 76.8%, P = 0.004), especially in earlier stages (stage IA, 72.6% vs. 100.0%; stage IB, 52.2% vs. 69.5%). However, the median tumor size treated by MIS was decreased in stage IB (20 mm vs. 17 mm, P = 0.015). Frequency of adjuvant treatment was also reduced in stage IB (56.5% vs. 37.3%, P = 0.016). Recurrence within 3 years, 3-year disease free survival and overall survival did not show significant difference; however, 3-year recurrence after MIS was significantly reduced in stage IB.

CONCLUSION

QC program enforced stricter patient selection criteria for MIS and positively affected clinical outcomes in cervical cancer patients who underwent surgery. Systemic monitoring should be considered for patient safety.

[A curriculum based certification of competence in gynaecologic surgical oncology]

OBJECTIVE

In France, we are lacking an identified pathway for training in gynaecological cancer surgery. The four competent French learned societies, the SFOG, the CNGOF, the SFCO and the SCGP, supported by the CNU of Obstetrics &Gynaecology- and UNICANCER, agreed to materialize this course and attest it by a certification awarded by a national jury.

MATERIAL AND METHODS

The national committee of certification in gynaecological oncology made up of 10 members, representing the 6 concerned organizations, set itself 5 objectives: the definition of the eligibility criteria for training centres; the determination of a check-list to be filled by the candidate; the determination of a targeted curriculum for the training in gynecological oncological surgery; the determination of the assets necessary for the certification of a candidate already in practice; and the practical organization of the certification.

RESULTS

Criteria for approval of centres for training included 150 gynaecological cancer cases per year, among which 100 excisional surgeries, including 20 advanced-stage ovarian cancers. For certification of candidate who followed the curriculum established by the committee or by validation of prior experience for an actual practitioner, a candidate must validate a logbook and fill out a checklist including 4 parts: theoretical and practical training; research and publications; teaching and subscription to a continuing education program. The accomplished elements of the logbook and the checklist will be evaluated by a score. The first certification session is planned for the end of 2021.

CONCLUSION

The optimisation of the surgical management of patients treated for gynaecological cancer is achieved through the identification of a training course and the certification, by a national jury, of the skills of surgeons who have completed it.

Extrapelvic bowel resection and anastomosis in cytoreductive surgery for ovarian cancer

Ovarian cancer is known as the second most common cause of death among gynecologic cancers. Survival outcome has been reported to be significantly associated with the efforts to minimize residual disease after cytoreductive surgery. As ovarian cancer often invades the small and large bowel without boundary, bowel surgery has been a crucial part of the cytoreductive surgery to achieve complete tumor removal. The scope of surgical resections has progressively expanded to include small and large bowel resections, making advanced surgical skills essential for gynecologic oncologists. In this review, we discuss the extra-pelvic bowel resection in cytoreductive surgery, with a focus on the regional anatomy and surgical techniques.
