Ovarian cancer | Top 20 novel treatment findings

Platinum agents benefit resistant ovarian cancer

The study found that patients with platinum-resistant ovarian carcinoma may derive significant benefit from reintroduction of platinum agents, with response rates of 36% for platinum-based therapy compared to 16% for non-platinum therapy.

Bevacizumab increases progression risk post-discontinuation

Bevacizumab treatment resulted in significantly better progression-free survival (PFS) during treatment compared to control, but PFS worsened after discontinuation, indicating a rebound effect.

BET and PD-L1 inhibitors combined ineffective

Only 2 patients (5.6%) exhibited a partial response to the treatment, indicating limited anti-tumor activity. While target engagement was confirmed, the combination did not significantly enhance tumor PD-L1 expression or anti-tumor immunity.

Ovarian tissue cryopreservation improves fertility in cancer patients

The technique has allowed for the resumption of endocrine function and fertility in certain populations, with live birth rates of up to 41% and an average endocrine function duration of 5 years post-transplantation.

Folate receptor alpha targets ovarian cancer

Patients with high FRα expression showed a median overall survival of 54.1 months compared to 36.3 months for those with low expression. The study suggests that combinations of FRα-targeting agents with other inhibitors may enhance therapeutic outcomes.

Olaparib and capivasertib combination effective

Of the 32 evaluable subjects, 6 (19%) achieved a partial response, with a higher response rate of 44.4% in endometrial cancer. Additionally, 7 (22%) patients had stable disease for more than 4 months, indicating durable activity.

Insulin therapy may raise ovarian cancer risk

The findings indicate a statistically significant causal association between genetically determined T1D and an increased risk of ovarian cancer, with insulin therapy acting as a mediating factor. This suggests that managing insulin therapy could be crucial in reducing the risk of OC in T1D patients.

Total parietal peritonectomy reduces peritoneal recurrence in advanced ovarian cancer.

Achieved a complete gross resection in 95.8% of patients; median progression-free survival (PFS) of 22 months; projected 3-year overall survival (OS) of 81.5%; low incidence of platinum resistant recurrence at 6.4%.

New HRD test improves Olaparib response

The novel nLST test demonstrated a lower failure rate and comparable progression-free survival (PFS) rates to the Myriad myChoice test, allowing more patients to receive conclusive results and potentially benefit from Olaparib treatment.

Vistusertib fails to enhance paclitaxel efficacy

Low tumor PTEN expression was associated with longer progression-free survival (PFS) in the wP+V arm, indicating potential predictive biomarker for treatment efficacy.

Study published: 2022-05-26

Circulating microRNA profiles predict better response to platinum chemotherapy in high-grade serous ovarian cancer patients.

The study found that circulating miRNA profiles can significantly predict the treatment-free interval of platinum (TFIp) in patients with HGSOC, with predictive models achieving an area under the curve of 0.944 for TFIp > 1 month, indicating high accuracy in predicting response to treatment.

Multiomic analysis improves ovarian cancer treatment

Patients with BRCA2 mutations and overexpressing cases demonstrated prolonged survival and higher chemotherapy response rates. The study highlights the survival benefit for cases with aberrations in HRR genes across all transcriptomic subtypes, indicating potential for improved treatment outcomes with targeted therapies.

Study published: 2022-01-07

Ovarian cancer prognosis linked to laterality

The findings indicate that laterality significantly impacts the incidence and prognosis of EOC, with unilateral tumors more common in certain subtypes and better prognosis observed on the right side compared to the left side. This suggests that considering laterality could enhance prognostic accuracy and treatment strategies.

Study published: 2023-08-28

Flutamide restores miR-449 in ovarian cancer

Flutamide treatment restored miR-449 expression in high-risk ovarian tissues, leading to decreased levels of CSF1R and AR, which are functional biomarkers linked to ovarian cancer risk. The treatment also inhibited the migration and proliferation of ovarian cancer cells in vitro.

Minimal COS reduces donor side effects

85% of women reported high satisfaction with minimal COS and would recommend or repeat the treatment. Minimal COS resulted in significantly less post-retrieval pain compared to conventional COS, with 33% experiencing no pain versus 6% in conventional COS.
