  • "It's Cancer: Colorectal Cancer with Sitaram Chilakamarry MD

    · "So... It's Cancer."

    Summary

    In this episode, the hosts introduce Sitaram Chilakamarry, MD, a colorectal cancer specialist, and discuss his background and interest in medicine. They then delve into the topic of colorectal cancer, providing statistics on its prevalence and mortality rates. They explain the anatomy of the colon and rectum and how colorectal cancer develops from the innermost lining of these organs. The discussion also touches on the role of genetics, diet, and inflammation in the development of colorectal cancer. The hosts emphasize the importance of early screening and detection to prevent advanced stages of the disease. The conversation explores different screening methods for colorectal cancer, including stool-based tests and direct visualization tests like colonoscopy. The FIT test, which checks for blood in the stool, is the most popular stool-based test. Colonoscopy is considered the gold standard for screening, but it is expensive and carries risks. The conversation also highlights the importance of healthy lifestyle choices in reducing the risk of colorectal cancer. Tobacco use and obesity are significant risk factors. The incidence of colorectal cancer is higher in smokers, and smoking causes inflammation throughout the body. The conversation concludes with a discussion of different cases of colorectal cancer and the next steps in diagnosis and treatment. In this conversation, Sitaram Chilakamarry discusses the process of diagnosing and staging colon and rectal cancer. He explains the importance of MMR testing, staging with CT scans and blood tests, and the role of surgery and chemotherapy in treatment. He also highlights the significance of regular colonoscopies for early detection and the potential for non-operative management of rectal cancer. Additionally, he mentions the promising use of immunotherapy in treating rectal cancer in patients with Lynch syndrome.

    What is Pancreatic Cancer, and how is it treated? With Eva Galka, M.D.

    [00:00] Intro and hello

    [01:30] Guest - Eva Galka, M.D. FACS: personal background and path to Surgical Oncology.

    [07:00] Pancreatic Cancer: typical patient

    [13:35] Clinical Presentation: how does someone know they have pancreatic cancer?

    [1:04:00] Chemotherapy

    [1:07:00] Breaking therapies & Studies on pancreatic cancer

    [1:15:00] Thank you and closing

    Key takeaways:

    1. Pancreatic cancer (specifically adenocarcinoma of the pancreas) is a fairly common, and very serious diagnosis, worldwide, with three basic categories meaning early (stage 1), late (stage 4), and intermediate (stages 2-3). Different approaches to the disease are based on which of those categories it falls into, and how healthy / able to tolerate treatment the patient may be.

       2. Resection is one's only/best chance for cure; however many cases are beyond respectability at diagnosis; and some are questionably resectable (borderline or locally advanced) and require upfront treatment before any attempt at resection. Even after resection it can come back, so extra treatments such as chemotherapy is almost always recommended.

       3.  Pancreas located in center of upper abdomen, surrounded by important other organs and blood vessels, making resection of tumors from it a very complex and technically demanding procedure, with significant risks of complications, even --not often but sometimes-- death.

       4.  Chemotherapy and radiation are somewhat effective; frequently necessary, but not AS effective as they can be in some other tumors/cancers..

       5.  The condition (adenocarcinoma of the pancreas) is best treated in specialized centers by specialized teams.

      6.  New treatments (such as immunotherapy and tumor vaccines) are being explored; but need to discuss with academic centers if applies to you. If you think you might be interested in being part of a trial, ask your treating physician and also view the show notes links below.

    Key takeaways:

    -- Palliative Care is a subspecialty and a team of professionals dedicated to improving the overall experience of a patient, family, and friends throughout the critically difficult moments of patient succumbing to disease.

    -- Comprised of a physician, nurse practitioner, psychologist, social worker, and chaplain; all specialized and with a professional focus in the field.

    -- Critical to establish "what are the goals of our treatment" and to ask "why are we doing what we are doing?"

    --Understanding, communication, expectations, hope, reality, and process.

    --Grief

    Key takeaways:

    -lung cancer is a heavy diagnosis; however great progress in its treatment has been made especially recently

    -lung cancer is among the most common and lethal, yet among the most preventable of tumors: by quitting smoking, or never starting.

    -new, powerful screening modalities in modern practices are low-dose Computed Tomography (“CT”) scans of the chest. Must meet specific guidelines and quit smoking to be able to benefit.

    -“Staging” of lung cancer (“Local, regional, distant”) determines treatment options and potential outcomes; baseline health status / lung function important.

    -Surgery, Chemotherapy, Immunotherapy, Radiation therapy are main treatment modalities

    -Optimal / Essential to have a primary care physician, and maintain a positive relationship with them.

    Key Takeaways:

    “Life” as we know and accept it is the product of an intricately organized set of self-sustaining bio-chemical processes working harmoniously, with memory and the ability to carry-on over time and over new generations (Paul’s best crack at the question of “what is life?”).

    Biological life is comprised of individual cells, which are extremely tiny and have three main parts:  cell membrane wall around it; cytoplasm filling it up; and a nucleus as the main office or command center of the cell containing the DNA / genetic code, which determines the structure and the behavior of the cells and the tissues. 

    In life, that DNA/genetic code acquires (or sometimes is born with) “defects” or “mutations” which alter the shape, function, and behavior of the cell; some types of mutations [particularly those responsible for the processes/jobs of cell signaling, cell growth, and cellular differentiation] result in derangements and loss of proper cellular function —which brings its own set of problems— and also, aggressive behaviors of local invasion and distal metastasis —which, untreated, can produce organ system failure and death.

    Normal cellular machinery is so complicated that there are 10,000 ways (my made up number) in which it can break down, which in short accounts for the great variability of ways...

    -- Blood in the urine (either visible to naked eye, or only under the microscope) is a common feature.

    -- Smoking (and some industrial exposures) important factors in its development

        -- "Transitional Cell" the most common type in USA and Europe; Squamous Cell (caused by a parasite called Shistosoma) also common in East Africa and Middle East

        -- Non-Muscle Invasive and Muscle Invasive frequently treated quite differently

        -- Chemotherapy, Radiotherapy, Immunotherapies available for Advanced Disease

        --  Important to not smoke, or quit smoking, to lower risk of disease.

    -- In East Africa and Middle East, a type of bladder cancer can occur because of a parasitic infection.

    · "So... It's Cancer."

    So doc, it’s Cancer? is a podcast dedicated to being a “how-to” manual for cancer patients and their friends and families. Each month we will work through different elements of the overall problem, “from soup to nuts” as they say, beginning at the beginning such as the the basics of what cancer is, who may be at risk, who is involved in the treatments, why treatments differ so much from one cancer to another, or even within the same type of cancer? The podcast will work through to the various possible outcomes, and quality of life.Why? Need for physician-led podcast series that is patient centric. It helps to have a chat with your physician, only, that chat is usually short, emotional, hard to remember, and often only a beginning. Hosts: Paul Roach - Surgical Oncology; Courtney Coke - Radiation Oncology; Pete Schlegel - Medical Oncology; Mike Riordan - Graphic Designer
