　View Summary

OBJECTIVE: To show how endoCUT (COMPANY, CITY, STATE, COUNTRY) mode can be safely managed with cervical conization. METHODS: Demonstration of the technique and explanation of endoCUT and soft coagulation mode with narrated video footage. Cervical conization is a therapeutic and diagnostic procedure performed for the diagnosis of cervical intraepithelial lesions and cervical cancer. Specific methods include cold scalpel, ultrasonically activated device and laser, and loop electrosurgical excision procedure (LEEP), which involves transpiration and partial excision. The endoCUT mode and soft coagulation in VIO3 (COMPANY, CITY, STATE, COUNTRY) were used to perform cervical conical resection safely and at low cost (Fig. 1). The endoCUT mode was originally developed for polypectomy in gastrointestinal endoscopy, where no counter traction can be applied [1,2]. RESULTS: The endoCUT mode approach to cervical conization with several key strategies to minimize blood loss and ensure safety: 1) incisions can be made in close contact; 2) resection can be performed with minimal contact with the lesion; 3) control of bleeding from the resected transection by soft coagulation; and 4) low running cost of endoCUT mode. CONCLUSION: Conventionally, cervical conical resection has been performed by using a device capable of making a close incision (cold scalpel, ultrasonically activated device and laser, and LEEP etc.), but there have been issues with bleeding control and cost. Here, we present a new technique using the endoCUT mode and several strategies for safe and effective resection.

　View Summary

Uterine leiomyosarcoma (LMS) is a gynecological malignancy with an extremely poor prognosis. Multiple new therapeutic agents, including pazopanib, trabectedin, and eribulin, have been clinically applied to treat uterine LMS, and their therapeutic effects are expected. We encountered one patient with advanced recurrent uterine LMS who achieved a partial response to a four-year treatment with eribulin. A 31-year-old woman was diagnosed with stage 2B LMS. After the first recurrence, Gemcitabine, Docetaxel (GD) therapy was administered, and complete response (CR) was achieved. However, 2 years and 10 months later, recurrence occurred at the vaginal cuff, and GD therapy and doxorubicin hydrochloride were administered, resulting in CR. Five months later, she experienced another recurrence at the same location and was treated with eribulin. To date, 53 courses of eribulin have been administered and are currently ongoing. Maintaining low neutrophil-to-lymphocyte ratio and low platelet-to lymphocyte ratio in this manner is considered to be one of the reasons why eribulin continues to be effective. We encountered a rare case in which eribulin was administered for the longest period of time, and produced an observable effect in uterine LMS.

　View Summary

Since the National Cancer Institute (NCI) alert of concurrent chemoradiotherapy, radiotherapy has been changed from external beam radiotherapy plus brachytherapy to platinum-based concurrent chemoradiotherapy. Therefore, concurrent chemoradiotherapy plus brachytherapy has become a standard treatment for locally advanced cervical cancer. Simultaneously, definitive radiotherapy has been changed gradually from external beam radiotherapy plus low-dose-rate intracavitary brachytherapy to external beam radiotherapy plus high-dose-rate intracavitary brachytherapy. Cervix cancer is uncommon in developed countries; hence, international collaborations have been critical in large-scale clinical trials. The Cervical Cancer Research Network (CCRN), created from the Gynecologic Cancer InterGroup (GCIG), has investigated various concurrent chemotherapy regimens and sequential methods of radiation and chemotherapy. Most recently, many clinical trials of combining immune checkpoint inhibitors with radiotherapy have been ongoing for sequential or concurrent settings. During the last decade, the method of standard radiation therapy has changed from three-dimensional conformal radiation therapy to intensity-modulated radiation therapy for external beam radiotherapy and from two-dimensional to three-dimensional image-guided approaches for brachytherapy. Recent improvements include stereotactic ablative body radiotherapy and MRI-guided linear accelerator (MRI-LINAC) using adaptive radiotherapy. Here we review the current progress of radiation therapy during the last two decades.

　View Summary

We report selected insufflation technique using direct bronchial insufflation to visualize the intersegmental plane during total thoracoscopic segmentectomy. Following the transection of the bronchus using a stapler, a small incision was created in the dissected target bronchus, and direct air insufflation was performed at the small incision site. The target segment was inflated, while the preserved segments appeared to collapse, and a demarcating line was visualized between the inflated and deflated lung parenchyma. This technique quickly identifies the anatomic intersegmental plane without warranting special equipment such as jet ventilation or indocyanine green (ICG). Furthermore, this method saves time in creating inflation-deflation lines.

　View Summary

BACKGROUND: One cause of the increase in cervical cancer rates in Japan is the long-term stagnation in the cervical cancer screening consultation rate. Therefore, improving the screening consultation rate is of urgent concern to reduce cervical cancer incidence. Self-collected human papilloma virus (HPV) tests have been successfully adopted in several countries, such as the Netherlands and Australia, as a measure of individuals who have not undergone cervical cancer screening in national programs. This study aimed to verify whether self-collected HPV tests presented an effective countermeasure for individuals who had not undergone the recommended cervical cancer screenings. METHODS: This study was conducted from December 2020 to September 2022 in Muroran City, Japan. The primary evaluated endpoint was the percentage of citizens who underwent cervical cancer screening at a hospital with positive self-collected HPV test results. The secondary endpoint was the percentage of included participants who were diagnosed with cervical intraepithelial neoplasia (CIN) or higher among those who visited a hospital and underwent cervical cancer screening. RESULTS: The included study participants were 7,653 individuals aged 20-50 years with no record of previous cervical cancer examination in the past 5 years. We mailed these participants information on self-administered HPV tests as an alternative screening procedure and sent the kit to 1,674 women who requested the test. Among them, 953 returned the kit. Among the 89 HPV-positive individuals (positive rate, 9.3%), 71 (79.8%) visited the designated hospital for an examination. A closer examination revealed that 13 women (18.3% of hospital visits) had a CIN finding of CIN2 or higher, among whom one each had cervical cancer and vulvar cancer, eight presented with CIN3, and three presented with CIN2; two cases of invasive gynecologic cancer were also identified. CONCLUSIONS: We conclude that the self-collected HPV tests showed a certain efficacy as a measure of individuals who had not undergone the recommended cervical cancer screening. We devised ways to have the unexamined patients undergo HPV testing and ensure that HPV-positive individuals visited the hospital. Despite a few limitations, our findings suggest the effectiveness of this public health intervention.

　View Summary

OBJECTIVES: Ipsilateral reoperation after pulmonary lobectomy is often challenging because of adhesions from the previous operation. We retrospectively examined the surgical outcome and prognosis of ipsilateral anatomical resection for lung cancer after pulmonary lobectomy using a multicentre database. METHODS: We evaluated the perioperative outcomes and overall survival of 51 patients who underwent pulmonary lobectomy followed by ipsilateral anatomical resection for lung cancer between January 2012 and December 2018. In addition, patients with stage I non-small-cell lung cancer (NSCLC) were compared with 3411 patients with stage I lung cancer who underwent pulmonary resection without a prior ipsilateral lobectomy. RESULTS: Ipsilateral anatomical resections included 10 completion pneumonectomies, 19 pulmonary lobectomies and 22 pulmonary segmentectomies. Operative time was 312.2 ± 134.5 min, and intraoperative bleeding was 522.2 ± 797.5 ml. Intraoperative and postoperative complications occurred in 9 and 15 patients, respectively. However, the 5-year overall survival rate after anatomical resection followed by ipsilateral lobectomy was 83.5%. Furthermore, in patients with c-stage I NSCLC, anatomical resection followed by ipsilateral lobectomy was not associated with worse survival than anatomical resection without prior ipsilateral lobectomy. CONCLUSIONS: Anatomical resection following ipsilateral lobectomy is associated with a high frequency of intraoperative and postoperative complications. However, the 5-year overall survival in patients with c-stage I NSCLC who underwent ipsilateral anatomical resection after pulmonary lobectomy is comparable to that in patients who underwent anatomical resection without prior pulmonary lobectomy.
