Molecular profiling identified actionable genomic alterations in 42.4% of advanced gynecologic cancer patients. However, only 12.6% received recommended targeted treatment, with 46% showing clinical benefit.
Area of Science:
- Oncology
- Genomics
- Precision Medicine
Background:
- The ProfiLER programme investigates molecular profiling in advanced refractory cancers.
- Gynaecological cancers represent a significant proportion of refractory malignancies.
Purpose of the Study:
- To identify actionable genomic alterations in gynaecological cancer patients within the ProfiLER programme.
- To evaluate the clinical efficacy of recommended targeted treatments (RTT) based on identified alterations.
Main Methods:
- Prospective, multicentric trial (NCT01774409) involving molecular profiling of tumour DNA.
- Targeted next-generation sequencing (69 genes) and whole genome array comparative genomic hybridisation.
- Molecular tumour board review to guide treatment strategies.
Main Results:
- 131 out of 279 (42.4%) gynaecological cancer patients had actionable genomic alterations.
- PIK3CA mutations (9.7%), KRAS mutations (5.4%), ERBB2 amplifications (3.9%), and CDKN2A deletions (3.2%) were most common.
- 12.6% of patients received RTT, with 20% partial response and 24% stable disease; median overall survival was 15.6 months for RTT recipients.
Conclusions:
- Molecular profiling is effective in identifying actionable genomic alterations in advanced refractory gynaecological cancers.
- A significant gap exists between identified alterations and RTT initiation.
- Clinical benefit was observed in 46% of patients receiving RTT, highlighting the potential of precision medicine.

Surface Tension, Capillary Action, and Viscosity
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...
