Background: Human papillomavirus (HPV) is a crucial etiological factor for cervical cancer (CC) development. From a diagnostic view-point, the consistent presence of HPV in CC allows the viral DNA to be used as a genetic marker. The aims of this study were to evaluate the presence, physical status and clinical significant of HPV DNA in circulation of CC patients.

This study reports the MTD, recommended phase 2 dose (RP2D), and preliminary efficacy of alpelisib or buparlisib used in combination with tamoxifen plus goserelin in premenopausal patients with hormone receptor-positive (HR þ), HER2-negative (HER2 À) advanced breast cancer (ABC). Patients and Methods: This study enrolled premenopausal women with HR þ , HER2 À ABC. Patients received tamoxifen (20 mg once daily) and goserelin acetate (3.6 mg every 28 days) with either alpelisib (350 mg once daily; n ¼ 16) or buparlisib (100 mg once daily; n ¼ 13) in 28-day cycles until MTD was observed. Results: The criteria for MTD were not met for both alpelisib and buparlisib. The RP2D of alpelisib and buparlisib in combination with tamoxifen and goserelin were 350 mg and 100 mg, respectively. Both combinations met protocol-specified criteria for tolerability. The most common grade 3/4 treatment-emergent adverse events (TEAE) were hypokalemia (12.5%), hyperglycemia (6.3%), and rash (6.3%) for alpelisib and alanine aminotransferase increase (30.8%), aspartate aminotransferase increase (23.1%), and anxiety (15.4%) for buparlisib. TEAEs led to treatment discontinuation in 18.8% and 53.8% of alpelisib-and buparlisib-treated patients, respectively. Progression-free survival was 25.2 months in the alpelisib group and 20.6 months in the buparlisib group. Conclusions: The RP2Ds of alpelisib and buparlisib were 350 mg and 100 mg, respectively. No unexpected safety findings were reported. Although an early-phase study, data suggest that alpelisib plus endocrine therapy may be a potentially efficacious treatment that warrants further evaluation for premenopausal patients with HR þ , HER2 À ABC.

To determine the effect of the deep inspiration breath-hold (DIBH) technique on left anterior descending coronary artery (LAD) region and heart dose in left breast cancer irradiation. Materials and Methods: Twenty-five left breast cancer patients who previously received breast-conserving surgery underwent computed tomography (CT) simulation with both free-breathing (FB) and DIBH techniques and four radiation treatment plans. The plan comprised the following with both the FB and DIBH techniques: whole breast (WB), and WB with internal mammary lymph nodes (WB+IMNs). The prescription dose was 50 Gy in 25 fractions. The doses to the LAD region, heart and lungs were compared. Moreover, in-field maximum heart distance (maxHD) and breast volume were analyzed for correlations with the mean heart dose (MHD). Results: In the WB plan with DIBH vs. FB techniques, the mean radiation doses to the LAD region, MHD, and the left lung V 20 were 11.48 Gy vs. 19.84 Gy (p < 0.0001), 2.95 Gy vs. 5.38 Gy (p < 0.0001), and 19.72% vs. 22.73% (p = 0.0045), respectively. In the WB+IMNs plan, the corresponding values were 23.88 Gy vs. 31.98 Gy (p < 0.0001), 6.43 Gy vs. 10.24 Gy (p < 0.0001), and 29.31% vs. 32.1% (p = 0.0009), respectively. MHD correlated with maxHD (r = 0.925) and breast volume (r = 0.6). Conclusion: The use of the DIBH technique in left breast cancer irradiation effectively reduces the radiation doses to the LAD region, heart and lungs. MHD is associated with maxHD and breast size.
