Summary
Robotic nipple-sparing mastectomy (RNSM) is a feasible and safe procedure with low complication rates and no early local recurrences. Further studies are needed to confirm long-term oncologic outcomes.
Area of Science:
- Oncologic Surgery
- Breast Surgery
- Robotic Surgery
Background:
- Robotic nipple-sparing mastectomy (RNSM) offers potential advantages in precision and cosmesis over open techniques.
- Limited data exist on the feasibility and safety of RNSM.
Purpose of the Study:
- To evaluate perioperative outcomes and early oncologic follow-up for patients undergoing RNSM.
- To assess the safety and efficacy of RNSM in a consecutive patient series.
Main Methods:
- Consecutive patients underwent RNSM with immediate robotic breast reconstruction via an axillary incision.
- Perioperative data, complications, pathological findings, and survival rates were recorded and analyzed.
- Follow-up data included local recurrence-free, disease-free, and overall survival.
Main Results:
- 94 RNSM procedures were performed on 73 women for various breast conditions.
- Mean operative time was 3 hours 32 minutes, with 89.4% undergoing one-step implant reconstruction.
- Low complication rates (4.3% reoperation, 1.1% flap necrosis) and no local recurrences were observed at a median 19-month follow-up.
Conclusions:
- RNSM demonstrates technical feasibility and safety with a low complication rate.
- Early oncologic outcomes are promising, with no local failures reported.
- Long-term follow-up is essential to validate oncologic safety; further trials are warranted.

02:07Tumor Progression
7.2K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

03:03mTOR Signaling and Cancer Progression
4.7K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

01:42Schemas
12.3K
A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

02:55The Nucleolus
10.3K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

02:53Reaction Rate
62.4K
The rate of reaction is the change in the amount of a reactant or product per unit time. Reaction rates are therefore determined by measuring the time dependence of some property that can be related to reactant or product amounts. Rates of reactions that consume or produce gaseous substances, for example, are conveniently determined by measuring changes in volume or pressure.
The mathematical representation of the change in the concentration of reactants and products, over time, is the rate...
