BACKGROUND: Video-assisted thoracoscopic surgery (VATS) lobectomy is the primary surgical treatment for lung cancer. A significant factor affecting postoperative recovery is prolonged air leak (PAL). Despite numerous clinical strategies could prevent and manage postoperative PAL, its incidence remains high. Phrenic nerve cryotherapy (PNC) temporarily inhibits phrenic nerve function, causing diaphragm elevation, which reduces thoracic cavity volume, enhances pleural apposition, and mitigates air leakage. This study investigates the efficacy of PNC in preventing postoperative PAL during VATS lobectomy. METHODS: A total of 108 eligible lung cancer patients who underwent surgery at the Department of Thoracic Surgery, The Affiliated Hospital of Inner Mongolia Medical University, from June 2023 to January 2025, were enrolled and randomly assigned to the control group (n=54) and the experimental group (n=54). The patients in both the two groups received VATS lobectomy and systematic lymph node dissection, with the experimental group also undergoing PNC during the operation. The baseline characteristics, intraoperative, postoperative indicators and dynamic changes in air leakage between the two groups were compared. RESULTS: The baseline clinical characteristics were comparable between the two groups (P>0.05). The incidence of pulmonary air leakage at 24 h after surgery (31.5% vs 29.6%) and the incidence of postoperative PAL (20.4% vs 14.8%) showed no significant differences between the two groups (P>0.05). The intraoperative air leak test to 24 hours after surgery revealed that air leakage ceased in 8 cases (32.0%) in the control group, compared to 14 cases (46.7%) in the experimental group. Moreover, during the progression from air leakage at 24 hours post-surgery to postoperative PAL, air leakage ceased in 6 cases (35.3%) in the control group and 8 cases (50.0%) in the experimental group, with a statistically significant difference (P<0.001). Compared to the control group, the patients in the experimental group exhibited more pronounced postoperative diaphragmatic elevation that recovered to a slightly higher than preoperative level by 3 mon after surgery. CONCLUSIONS The combination of PNC and active lung repair can serve as an important intervention for patients at high risk of intraoperative air leakage, reducing the occurrence of postoperative PAL.

PURPOSE: The purpose of this study was to examine the effects of oral cryotherapy on oral mucositis, reactive oxygen series, inflammatory cytokines, and oral comfort in patients undergoing chemotherapy for gynecologic cancers. METHODS: Participants were randomly assigned to the experimental group (n=25, receiving oral cryotherapy during chemotherapy) and the control group (n=25, receiving the usual care consisting of 0.9% normal saline gargles three times before meals). Oral mucositis was assessed using the oral assessment guide, while oral comfort was assessed using the oral perception guide. Reactive oxygen series was measured as total oxidant stress, and the level of two inflammatory markers, interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α), were examined. The data were analyzed using t-test, chi-square test, Fisher's exact test, Mann-Whitney U-test, and repeated measures analysis of variance. RESULTS: There was a significant difference in the oral mucositis score, reactive oxygen series score, TNF-α level, and oral comfort score between the two groups, and there were significant changes over time and in the group-by-time interactions. There was a significant difference in the IL-6 score between the two groups, but there were no significant changes over time or in the group-by-time interactions. CONCLUSION: The study results revealed that oral cryotherapy was more effective than the usual care regime of normal saline gargles for reducing oral mucositis, reactive oxygen series, and inflammatory cytokines and for improving oral comfort in gynecologic cancer patients undergoing chemotherapy.

BACKGROUND: Bronchoscopy is a useful diagnostic and therapeutic tool. However, the clinical use of high-flow nasal cannula (HFNC) in adults with acute respiratory failure for diagnostic and invasive procedures has not been well evaluated. We present our experiences of well-tolerated diagnostic bronchoscopy as well as cases of improved saturation in hypoxaemic patients after a therapeutic bronchoscopic procedure. METHODS: We retrospectively reviewed data of hypoxaemic patients who had undergone bronchoscopy for diagnostic or therapeutic purposes from October 2015 to February 2017. RESULTS: Ten patients (44–75 years of age) were enrolled. The clinical purposes of bronchoscopy were for diagnosis in seven patients and for intervention in three patients. For the diagnoses, we performed bronchoalveolar lavage in six patients. One patient underwent endobronchial ultrasonography with transbronchial needle aspiration of a lymph node to investigate tumour involvement. Patients who underwent bronchoscopy for therapeutic interventions had endobronchial mass or blood clot removal with cryotherapy for bleeding control. The mean saturation (SpO2) of pre-bronchoscopy in room air was 84.1%. The lowest and highest mean saturation with HFNC during the procedure was 95% and 99.4, respectively. The mean saturation in room air post-bronchoscopy was 87.4%, which was 3.3% higher than the mean room air SpO2 pre-bronchoscopy. Seven patients with diagnostic bronchoscopy had no hypoxic event. Three patients with interventional bronchoscopy showed improvement in saturation after the procedure. Bronchoscopy was well tolerated in all 10 cases. CONCLUSION: This study suggests that the use of HFNC in hypoxaemic patients during diagnostic and therapeutic bronchoscopy procedures has clinical effectiveness.

For the several decades, the treatment of clinically localized prostate cancers has been largely represented by surgery, radiotherapy, and observation. Until recently, this has not changed much. In particular, curative treatment through surgery or radiotherapy is considered to be of no great benefit in elderly patients with low-risk groups. Thus, these strategies are recommended only in moderate or high-risk patients with a life expectancy of 10 years or more. In general, surgery and radiotherapy have been reported to be similar in terms of oncologic outcomes, but the level 1 evidence was lacking to support this to date. Recent advances in imaging modalities have led to the introduction of treatments for the concept of focal therapy, such as high-intensity frequency ultrasound or cryotherapy. Subsequently, positive results have been reported in terms of functional outcomes. However, the level of evidence is not high due to the short follow-up period and the absence of large-scale prospective studies. For the reasons described above, counseling and decision-making were not straightforward. Consequently, the treatment strategy for each individual patient was determined mainly on the risk of incontinence, erectile dysfunction, or other adverse effects of radiotherapy. To overcome these limitations, substantial studies have been reported evaluating survival outcomes and complications following treatments of localized prostate cancer for the past several years. In this review, we aimed to summarize recent literatures on surgery, radiotherapy, and expectant management, which have been the mainstays of treatment for localized prostate cancer; and introduce several treatments for the concept of focal therapy.

OBJECTIVE: To investigate the progression risk of atypical squamous cells of undetermined significance (ASCUS) with different clinical managements. METHODS: Women with their first diagnosis of ASCUS cytology were retrieved from the national cervical cancer screening database and linked to the national health insurance research database to identify the management of these women. The incidences of developing cervical intraepithelial neoplasia grade 3 and invasive cervical cancer (CIN3+) were calculated, and the hazard ratios (HRs) were estimated using a Cox proportional hazards model. This study was approved by the Research Ethics Committee of the National Taiwan University Hospital and is registered at ClinicalTrials.gov (Identifier: NCT02063152). RESULTS: There were total 69,741 women included. Various management strategies including colposcopy, cervical biopsies and/or endocervical curettage, and cryotherapy, failed to reduce the risk of subsequent CIN3+ compared with repeat cervical smears. Loop electrosurgical excision procedure/conization significantly decreased risk of subsequent CIN3+ lesions (HR=0.22; 95% confidence interval [CI]=0.07–0.68; p=0.010). Women in their 40s–50s had an approximately 30% risk reduction compared to other age groups. Women with a previous screening history >5 years from the present ASCUS diagnosis were at increased risk for CIN3+ (HR=1.24; 95% CI=1.03–1.49; p=0.020). CONCLUSION: In women of first-time ASCUS cytology, a program of repeat cytology can be an acceptable clinical option in low-resource settings. Caution should be taken especially in women with remote cervical screening history more than 5 years.

Circumscribed palmar or plantar hypokeratosis is a rare condition characterized by the occurrence of an erythematous, well-circumscribed, and depressed macule or patch on the palms or soles. Histopathologically, it is characterized by sharp, stair-like abrupt thinning of the horny layer between the affected and unaffected skin. The pathogenesis of this condition remains unclear. Recently, the human papilloma virus has been implicated as a possible etiological contributor. Circumscribed palmar or plantar hypokeratosis usually shows a benign course. Previous reports have not described malignant changes in these lesions. However, its association with actinic keratosis has been reported in a previous case. We report a case of circumscribed palmar hypokeratosis showing bowenoid epidermal change with expression of the human papilloma virus types 6 and 16 in a patient who was successfully treated with ingenol mebutate gel and cryotherapy.

Esophageal cancer has a poor overall prognosis and is frequently diagnosed at a late stage. Conventional treatment for metastatic esophageal cancer involves chemotherapy and radiation. Local disease control plays a significant role in improving survival. Endoscopic spray cryotherapy is a novel modality that involves freezing and thawing to produce local ablation of malignant tissue via ischemic mechanisms. Spray cryotherapy has been shown to be effective, particularly for early T-stage, superficial esophageal adenocarcinomas. We present the case of a 72-year-old-male with locally recurrent stage IV esophageal adenocarcinoma and long-term survival of 7 years to date, with concurrent chemoradiation and serial cryoablation. He remains asymptomatic and continues to undergo chemotherapy and sequential cryoablation. The findings highlight the long-term safety and efficacy of cryotherapy in combination with chemoradiation, and suggest that cryoablation may have an additive role in the treatment of advanced stage esophageal adenocarcinoma.
