The resection is an attempt to remove a cancer tumor so that no portion of the malignant growth extends past the edges or margin of the removed tumor and surrounding tissue. These are retained after the surgery and examined microscopically by a pathologist to see if the margin is indeed free from tumor cells (called "negative"). If cancerous ...
Minimal residual disease (MRD), also known as Molecular residual disease, is the name given to small numbers of cancer cells that remain in a person either during or after treatment when the patient is in remission (no symptoms or signs of disease). Sensitive molecular tests are either in development or available to test for MRD.
Phoenix rising is a process by which dead cells send signals that promote growth and division, generating new cells. [25] After a tissue injury, stem cells present in and around the injured tissue play a crucial role in replenishing the damaged ones.
Disseminating cancer cells can proliferate or become dormant depending on the microenvironment and factors such as the ERK/p38 ratio. Dormancy is a stage in cancer progression where the cells cease dividing but survive in a quiescent state while waiting for appropriate environmental conditions to begin proliferation again. [1]
Chemotherapy often follows Mohs surgery to eliminate the residual superficial basal-cell carcinoma after the invasive portion is removed. 5-fluorouracil has received FDA approval. Removing the residual superficial tumor with surgery alone can result in large and difficult to repair surgical defects.
A study of the usefulness of platinum-based chemotherapy as an adjuvant after surgery of stage I patients showed that patients with stage 1A who had no residual disease in the hysterectomy specimen had no recurrence regardless if chemotherapy was used or not, however, patients with stage 1A disease with residual disease in the hysterectomy ...
After Greg had eight rounds of chemo, as well as the stomach-removal surgery, he was cancer-free for about a year. Then the cancer came back in the peritoneum, the lining of his abdomen.
The clinical quotes for cure rate of Mohs surgery are from 97% to 99.8% after 5 years for newly diagnosed basal-cell cancer (BCC), decreasing to 94% or less for recurrent basal-cell cancer. Radiation oncologists quote cure rates from 90 to 95% for BCCs less than 1 or 2 cm, and 85 to 90% for BCCs larger than 1 or 2 cm.
