Cancer heterogeneity represents the main issue for defining an effective treatment in clinical practice, and the scientific community is progressively moving towards the development of more personalized therapeutic regimens. Radiotherapy (RT) remains a fundamental therapeutic treatment used for many neoplastic diseases, including breast cancer (BC), where high variability at the clinical and molecular level is known. The aim of this work is to apply the generalized linear quadratic (LQ) model to customize the radiant treatment plan for BC, by extracting some characteristic parameters of intrinsic radiosensitivity that are not generic, but may be exclusive for each cell type. We tested the validity of the generalized LQ model and analyzed the local disease-free survival rate (LSR) for breast RT treatment by using four BC cell cultures (both primary and immortalized), irradiated with clinical X-ray beams. BC cells were chosen on the basis of their receptor profiles, in order to simulate a differential response to RT between triple negative breast and luminal adenocarcinomas. The MCF10A breast epithelial cell line was utilized as a healthy control. We show that an RT plan setup based only on α and β values could be limiting and misleading. Indeed, two other parameters, the doubling time and the clonogens number, are important to finely predict the tumor response to treatment. Our findings could be tested at a preclinical level to confirm their application as a variant of the classical LQ model, to create a more personalized approach for RT planning.

Breast cancer is the most prevalent female malignancy. When diagnosed at young age (up to 40 years), negative clinical, morphological and prognostic features are noted. A non-randomized retrospective trial (n=500) was performed to evaluate different scenarios of breast cancer hormone therapy in young patients. Ovarian suppression in young patients is shown to statistically improve prognosis. Disease-free survival rate values are observed to decrease in patients without ovarian suppression in comparison with any type of ovarian suppression, especially at a remote follow-up (after 60 months). Menstrual function resumption and no amenorrhea after chemotherapy significantly decrease disease-free survival rate values in young patients.

Objective: To analyze the clinical effect of primary small liver cancer under radiofrequency ablation (RFA) and surgical resection (SR) treatment, and to explore the best application timing of the two treatment methods. Methods: Randomly controlled clinical trials (RCT) of percutaneous radiofrequency ablation and surgical resection for the treatment of small liver cancer in various databases were searched according to the established search strategy, and Meta data was analyzed based on RevMan5.3 software provided by Cochrane collaborative organization. Results: A total of 10 articles were included in this study, including 1396 patients, 699 in the RFA group and 697 in the SR group. Meta-analysis results showed that the two groups had no statistical difference in overall survival rate at 1 and 3 years, 1-year disease-free survival rate, and 1-year recurrence rate (P>0.05). The 3-year disease-free survival rate of the RFA group was lower than that of the SR group, and the 3-year recurrence rate was higher than that of the SR group. The higher postoperative complication rate tended to the SR group, and the differences were statistically significant. (P<0.05). Conclusion: For short-term efficacy, radiofrequency ablation and surgical resection show consistency; for long-term efficacy, surgical resection is more effective.

Background There is no standard adjuvant chemotherapy to prevent recurrent cholangiocarcinoma (CCA), a rare cancer with poor prognosis. We assessed the efficacy and safety of GEMOX on intrahepatic and hilar CCA with high-risk factors after curative surgery. Patients and Methods Twenty two patients (mean age: 57 years old) with CCA received 6 cycles of GEMOX: gemcitabine 1,000 mg/m2 on day 1 and oxaliplatin 85 mg/m2 on day 2, q3w after a curative surgery. Results All patients completed 6 cycles of GEMOX. EGFR membranous expression was present in 20 CCA. The 5-year survival rate was 56% (CI 95%: 25.7–85.4); 2-year disease free survival rate was 28% (CI 95%: 3.4–52.6). Median time to progression was 15 months. The rate of recurrence after surgery and chemotherapy was 63% (14/22). Two patients died of disease progression. Twelve patients received cetuximab/GEMOX at the time of relapse. Six died after 12 months (9–48 months), three are still alive suggesting a clinical applicability of EGFR inhibitors in CCA. Conclusion Adjuvant chemotherapy with GEMOX alone seems ineffective in intrahepatic and hilar CCA with a high risk of relapse. Additional studies including targeted therapies to circumvent such poor chemosensitivity are needed.

<b><i>Objective:</i></b> The aim of this study was to evaluate the long-term outcomes and the factors related to patient prognosis. <b><i>Materials and Methods:</i></b> We retrospectively analyzed patients treated at the Department of Gynecology, Sun Yat-sen University Cancer Center, between January 1, 1968, and December 12, 2018. <b><i>Results:</i></b> A total of 107 patients were identified. Of all patients, 79 (73.8%) presented with stage I disease, 14 (13.1%) stage II, 13 (12.2%) stage III, and 1 (0.9%) stage IV. All patients received surgery, with 70 (65.4%) undergoing fertility-sparing surgery (FS) and 37 (34.6%) nonfertility-sparing surgery (NFS). Ninety patients received postoperative chemotherapy. Nine of the 43 cases with a lymphadenectomy had metastasis (20.9%). The median follow-up time was 132 months (range, 1–536 months). The overall 5-year and 10-year survival was 95.1% and 91.7%, respectively. The 10-year survival rate for stage I and II–IV patients was 96.1% and 79.1%, respectively (<i>p</i> = 0.008). For the patients undergoing FS and NFS, the 10-year disease-free survival rate was 82.3% and 88.0%, respectively (<i>p</i> = 0.403). The 10-year disease-free survival rate for patients with or without lymphadenectomy was 95.1% and 78.4%, respectively (<i>p</i> = 0.040), and it was 92.5% and 76.0%, respectively (<i>p</i> = 0.041), for those with or without omentectomy. Fifteen patients relapsed, and 4 of them (26.7%) had recurrence in the lymph nodes. Eleven of the 15 relapsed patients (73.3%) had been successfully salvaged. <b><i>Limitations:</i></b> As a study of a rare disease, our analysis was limited by its small sample size and the deemed disadvantage of a retrospective study. <b><i>Conclusion:</i></b> Excellent treatment results can be achieved in dysgerminoma patients who received proper treatment. Lymphadenectomy may improve patient survival. Relapsed patients can also be successfully salvaged.
