Treatments for cancers of the pancreas, liver, and biliary system vary depending on factors like the stage of cancer, the patient's overall health, and specific characteristics of the tumor. Here are some common treatment modalities:

​

Surgery: Surgical options include:

• Pancreaticoduodenectomy (Whipple procedure): This is often performed for pancreatic cancer that has not spread beyond the pancreas. It involves removing the head of the pancreas, part of the small intestine, the gallbladder, part of the stomach, and nearby lymph nodes.

• Distal pancreatectomies: Removing part the left portion of the pancreas. 

• Liver resection: In cases of liver cancer, surgery may involve removing the tumor along with a portion of healthy liver tissue.

• Biliary resection: Surgery to remove the affected portion of the bile duct may be performed for bile duct cancers.

​​

Chemotherapy: Chemotherapy drugs can be used to kill cancer cells or stop them from growing. It may be administered before surgery (neoadjuvant chemotherapy) to shrink the tumor, after surgery (adjuvant chemotherapy) to kill any remaining cancer cells, or as the primary treatment for advanced cases.

​

Radiation therapy: This treatment uses high-energy rays to kill cancer cells. It may be used alone or in combination with surgery and/or chemotherapy. Techniques like stereotactic body radiation therapy (SBRT) or intensity-modulated radiation therapy (IMRT) can be used to precisely target tumors while minimizing damage to surrounding healthy tissue.

​

Targeted therapy: This approach involves using drugs or other substances to specifically target cancer cells while minimizing damage to normal cells. Targeted therapies may include drugs that interfere with specific molecules involved in tumor growth and progression.

​

Immunotherapy: Immunotherapy drugs work by helping the body's immune system recognize and attack cancer cells. Immune checkpoint inhibitors, CAR-T cell therapy, and therapeutic cancer vaccines are among the immunotherapy approaches being studied for pancreatic, liver, and bile duct cancers.

​

Palliative care: In cases where the cancer is advanced and cannot be cured, palliative care focuses on providing relief from symptoms, improving quality of life, and offering support for both patients and their families. This may include pain management, nutritional support, and psychological support.

​​

Clinical trials: Participation in clinical trials can provide access to experimental treatments that may offer new hope for patients with pancreatic, liver, or biliary system cancers. These trials test new drugs, therapies, or treatment combinations to determine their safety and effectiveness.

​

It's important for patients to discuss their treatment options with a multidisciplinary team of healthcare providers, including surgeons, medical oncologists, radiation oncologists, and other specialists, to develop a personalized treatment plan tailored to their individual needs.

BENIGN CONDITIONS OF THE PANCREAS, LIVER AND BILE DUCTS

Treatment for benign conditions of the pancreas, liver, and bile ducts depends on the specific condition and its severity. Here are some common benign conditions and their treatment approaches:

Pancreatitis:

• Acute Pancreatitis: Treatment often involves hospitalization, where patients receive intravenous fluids to prevent dehydration and may be kept nil by mouth to allow the pancreas to rest. Pain relief medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or opioids, may be prescribed. In severe cases, patients may require nutritional support via a feeding tube. Identifying and addressing the underlying cause, such as gallstones or alcohol use, is also important.

• Chronic Pancreatitis: Management focuses on pain relief, pancreatic enzyme replacement therapy to aid digestion, dietary modifications to avoid triggering factors, and lifestyle changes such as abstaining from alcohol and quitting smoking. In some cases, surgery may be necessary to alleviate blockages or remove damaged portions of the pancreas.

Liver Conditions:

• Symptomatic liver cysts: Surgery is sometimes indicate to relieve symptoms related to large liver cysts.

Biliary Conditions:

• Gallstones: Treatment of symptomatic patients (cholecystitis) involves surgical removal of the gallbladder (cholecystectomy) if symptoms are severe or complications arise.

• Biliary Strictures: Treatment options include endoscopic procedures to widen narrowed bile ducts or surgery to remove or bypass the strictures.

SKIN CANCERS AND SARCOMAS

Cutaneous cancers, which include various types of skin cancers, are typically treated based on the type of cancer, its stage, location, and other individual factors. Here are some common treatment modalities for cutaneous cancers:

​

Surgery:

• Excision: This involves surgically removing the cancerous lesion along with a margin of healthy tissue to ensure complete removal.

• Wide local excision: For melanoma or other larger or deeper lesions, a wider margin of surrounding tissue may be removed to ensure complete removal of cancer cells.

• Sentinel lymph node biopsy and lymphadenectomy: Removal of lymph nodes to determine the stage of the cancer.

​

Targeted therapy:

• For advanced or metastatic melanoma, targeted therapy drugs may be used to block specific molecules involved in cancer growth, such as BRAF inhibitors or immune checkpoint inhibitors.​

Chemotherapy:

• Systemic chemotherapy may be used for advanced or metastatic melanoma or other skin cancers that have spread beyond the skin. However, it's less commonly used for most cutaneous cancers due to limited effectiveness and significant side effects.
