    BACKGROUND: Female physicians with children often work fewer hours and take fewer shifts due to additional family responsibilities. This can contribute to a gender pay gap in the medical profession. However, limited research in Japan has quantitatively examined the factors contributing to this gap. This study aims to address this gap in the literature. METHODS: We analyzed the alumni data from a medical school in Hokkaido, Japan, for 260 physicians (198 males and 62 females). We used multivariable regression models to identify factors influencing earnings from medical practice, with a focus on gender, work schedules, parenthood, and any career interruptions related to childcare. RESULTS: Our analysis revealed a 25.0% earnings gap between male and female physicians. Nearly all female physicians with children experienced career interruptions due to childcare, while this was uncommon for male physicians. When these childcare-related interruptions were factored in, the gender pay gap narrowed by 9.7%. After adjusting for work schedules and specialty choices, female physicians with children still earned 37.2% less than male physicians, while those without children earned only 4.4% less. This suggests that motherhood is a significant driver of the gender pay gap among physicians. CONCLUSIONS: These findings highlight the negative impact of motherhood on female physicians' earnings. This emphasizes the need for policy measures to mitigate the disadvantages faced by mothers in the medical profession.

    PURPOSE: Since December 2019, coronavirus disease 2019 (COVID-19) has spread rapidly across the world. During the pandemic, physicians in our hospital have had to respond both to the issue of treating the patients and the increasing domestic burden associated with social disruption. The purpose of this study was to assess how much the burden on our doctors, especially female doctors, was increasing. MATERIAL AND METHODS: The Physicians' Career Support Committee in Sapporo Medical University conducted a questionnaire survey. The questionnaire inquired about a wide range of subjects with regard to working style and family life during the first and second waves of the COVID-19 pandemic, and was sent to all medical/dental physicians working in Sapporo Medical University. RESULTS: A total of 266 (42.7%) physicians in our hospital responded to our questionnaire and the data for 264 data were analyzed. The total numbers of males, females, and others, including those who did not want to specify, were 178 (67.4%), 82 (31.0%), and 4 (1.5%), respectively. Among them, 62 (23.5%) and 23 (8.7%) answered that their domestic burden was slightly or markedly increased. The increase in the domestic burden showed a significant difference between genders (p = 0.04). Even after correction for background differences using multivariate analysis, being female (p<0.001), having child dependents (p<0.001), and treating COVID-19 patients (p = 0.03) were significantly related to an increased domestic burden. Regarding family style, 58.1% of the physician-fathers were from two-income families (i.e., families with both parents in employment), and they answered that their partner mainly cared for the children. In contrast, 97.3% of physician-mothers were from two-income families, and 94.6% of the physician-mothers had to take care of children by themselves. CONCLUSION: Physician-mothers are caught in a dilemma between an increased home burden and clinical duties in the hospital, with a significantly higher ratio than physician-fathers during the pandemic. As we showed, female doctors could have not continued their careers and take responsible positions in the same way as male doctors. This is a social risk in the timing of a crisis, such as a pandemic.

  • Expression of hepatocyte growth factor in prostate cancer may indicate a biochemical recurrence after radical prostatectomy.

    We previously found that prostate cancer stem-like cells (CSCs)/cancer-initiating cells (CICs) express hepatocyte growth factor (HGF) and that the HGF/c-MET proto-oncogene product (c-MET) signal has a role in the maintenance of prostate CSCs/CICs in an autocrine fashion. HGF is, thus, a novel marker for prostate CSCs/CICs. We hypothesized that high expression of HGF might be related to early recurrence of prostate cancer after radical prostatectomy, and the purpose of the present study was to evaluate the relationship between expression of HGF in prostate tissues and biochemical recurrence after radical prostatectomy. One hundred-one patients with prostate cancer who underwent open or laparoscopic radical prostatectomy from November 2008 to October 2011 with an adequate prostate-specific antigen (PSA) follow-up period, were investigated. Immunohistochemical staining of HGF was compared to biochemical recurrence after radical prostatectomy. Patients with tumors exhibiting HGF positivity of 5% or more had a significantly shorter biochemical recurrence-free period than that of patients whose tumor HGF positivity was less than 5% (p=0.001). In multivariate Cox regression, preoperative PSA and HGF positivity were independent predictors of biochemical recurrence following prostatectomy. Our finding suggests a direct link between expression of HGF, a novel prostate marker of CSCs/CICs, and biochemical recurrence after radical prostatectomy in patients with prostate cancer.

    本研究の目的は前立腺癌のがん幹細胞の同定と解析および治療法の樹立である。ヒト前立腺癌細胞株22Rv1に対してALDH1活性分析を行ったところ、ALDH1活性の高い細胞集団にがん幹細胞が多く含まれ、hepatocyte growth factor(HGF)を分泌することがわかった。前立腺癌患者の摘出標本のHGF免疫染色を行い術後のPSA再発との関係を調べた結果、HGF陽性率5%以上の症例群は5%未満の症例に比較し有意にPSA再発までの期間が短かった。HGFの抑制が癌の再発回避につながる可能性がある。
