All treatments can have side effects. It’s important to know what side effects to expect from squamous cell skin cancer therapies and how to work with your healthcare team to manage them.
Surgery carries both short- and long-term risks. This section will not cover short-term side effects of surgery such as bleeding, adverse reactions to medications, or difficulty closing the wound, because these are associated with the immediate surgical event, and your doctor will likely give you information after surgery addressing these issues.
Surgery can affect different body systems. Sensory nerve damage can occur with surgery, leading to localized numbness, a sensation of pins and needles, or burning or severe pain. Motor nerve damage can also occur, resulting in weakness or paralysis. In general, if the involved area is small, nerve damage may improve or resolve in approximately 12 months. However, sometimes the neurologic symptoms remain. Another intermediate- to longer-term complication that can occur after surgery is wound infection. The wound can also break down, or healing can be delayed. It’s important to keep your follow-up appointments with your surgery team and report any side effects immediately. Team members can offer strategies to address some of these complications.
Lymphedema (lim·fuh·dee·muh) is an accumulation of lymph in the soft tissue (swelling) caused by the damage/removal of lymph nodes/lymphatic channels. It can occur either short term or long term for patients with squamous cell skin cancer who have had more extensive surgery. A lymphedema therapist can help with skin care, massage, bandaging, exercises, or a compression garment. This treatment is called complex decongestive therapy (CDT). For more about specific lymphedema management, see the “Treating Lymphedema” section of the American Cancer Society website: https://www.cancer.org/treatment/treatments-and-side-effects/physical-side-effects/lymphedema/for-people-with-lymphedema.html
One of the biggest challenges with advanced squamous cell skin cancer (beyond the threat of poor overall outcomes) is the potential for unsightly cosmetic results. This can include loss or darkening of skin color, suture marks, or excessive scarring. When the squamous cell skin cancer is highly invasive, the degree of disfigurement can be substantial. Having a good reconstruction plan and follow-up with your surgeon is important. In one study, squamous cell skin cancer patients reported reduced quality of life one month after surgery because of pain, functional challenges, and cosmetic challenges. Importantly, this response improved over the course of the year after surgery. However, for patients with disfigurement, an aggressive plan for reconstruction and emotional support and counseling can be very important. Look in our RESOURCES section for support groups and resources specifically available to help you address the cosmetic impact of cancer and the emotional aspects of a change in your appearance.
Side effects of radiation are usually restricted to the area that has been radiated and can include:
It’s important to talk with your radiology team about strategies to deal with these side effects. Some self-care approaches you can take include:
Immune checkpoint inhibitors such as cemiplimab and pembrolizumab rev up the immune system and cause a range of side effects. These can be considered autoimmune in nature. The figure below shows the body systems that can be involved.
Concerning side effects associated with immunotherapy are lung, liver, skin, neurologic, cardiac, and ocular problems; gastrointestinal inflammation; and hormonal problems affecting glands like the adrenal, pituitary, thyroid glands, and the pancreas. Serious side effects occurred in approximately one quarter or less patients in immunotherapy clinical trials.
With immunotherapy, reducing the dosage is not generally recommended. The management of these side effects typically involves stopping immunotherapy and then managing the side effect. In many of the moderate cases, corticosteroids are used to quiet the immune system, after which immunotherapy can be restarted. But in severe cases, the drug may need to be discontinued.
The following educational videos, courtesy of the IO Essentials Initiative, feature oncology experts discussing various side effects associated with immunotherapy.
