Chemotherapy is a type of cancer treatment that uses one or more anti-cancer drugs as part of a standardized chemotherapy regimen. Chemotherapy may be given with a curative intent or it may aim to prolong life or to reduce symptoms. Chemotherapy is one of the major categories of the medical discipline specifically devoted to pharmacotherapy for cancer, which is called medical oncology.
Lymphoma is a group of blood and lymph tumors that develop from lymphocytes. The name typically refers to just the cancerous versions rather than all such tumours. Signs and symptoms may include enlarged lymph nodes, fever, drenching sweats, unintended weight loss, itching, and constantly feeling tired. The enlarged lymph nodes are usually painless. The sweats are most common at night.
Nabilone, sold under the brand name Cesamet among others, is a synthetic cannabinoid with therapeutic use as an antiemetic and as an adjunct analgesic for neuropathic pain. It mimics tetrahydrocannabinol (THC), the primary psychoactive compound found naturally occurring in Cannabis.
Cyclophosphamide (CP), also known as cytophosphane among other names, is a medication used as chemotherapy and to suppress the immune system. As chemotherapy it is used to treat lymphoma, multiple myeloma, leukemia, ovarian cancer, breast cancer, small cell lung cancer, neuroblastoma, and sarcoma. As an immune suppressor it is used in nephrotic syndrome, granulomatosis with polyangiitis, and following organ transplant, among other conditions. It is taken by mouth or injection into a vein.
The era of cancer chemotherapy began in the 1940s with the first use of nitrogen mustards and folic acid antagonist drugs. The targeted therapy revolution has arrived, but many of the principles and limitations of chemotherapy discovered by the early researchers still apply.
Anthracyclines are a class of drugs used in cancer chemotherapy that are extracted from Streptomyces bacterium. These compounds are used to treat many cancers, including leukemias, lymphomas, breast, stomach, uterine, ovarian, bladder cancer, and lung cancers. The first anthracycline discovered was daunorubicin, which is produced naturally by Streptomyces peucetius, a species of Actinomycetota. Clinically the most important anthracyclines are doxorubicin, daunorubicin, epirubicin and idarubicin.
Epirubicin is an anthracycline drug used for chemotherapy. It can be used in combination with other medications to treat breast cancer in patients who have had surgery to remove the tumor. It is marketed by Pfizer under the trade name Ellence in the US and Pharmorubicin or Epirubicin Ebewe elsewhere.
Procarbazine is a chemotherapy medication used for the treatment of Hodgkin's lymphoma and brain cancers. For Hodgkin's it is often used together with chlormethine, vincristine, and prednisone while for brain cancers such as glioblastoma multiforme it is used with lomustine and vincristine. It is typically taken by mouth.
Vinblastine (VBL), sold under the brand name Velban among others, is a chemotherapy medication, typically used with other medications, to treat a number of types of cancer. This includes Hodgkin's lymphoma, non-small-cell lung cancer, bladder cancer, brain cancer, melanoma, and testicular cancer. It is given by injection into a vein.
MOPP is a combination chemotherapy regimen used to treat Hodgkin lymphoma. The acronym is derived from the component drugs of the regimen:
Dacarbazine, also known as imidazole carboxamide and sold under the brand name DTIC-Dome, is a chemotherapy medication used in the treatment of melanoma and Hodgkin's lymphoma. For Hodgkin's lymphoma it is often used together with vinblastine, bleomycin, and doxorubicin. It is given by injection into a vein.
CHOP is the acronym for a chemotherapy regimen used in the treatment of non-Hodgkin lymphoma. CHOP consists of:
Adjuvant therapy, also known as adjunct therapy, adjuvant care, or augmentation therapy, is a therapy that is given in addition to the primary or initial therapy to maximize its effectiveness. The surgeries and complex treatment regimens used in cancer therapy have led the term to be used mainly to describe adjuvant cancer treatments. An example of such adjuvant therapy is the additional treatment usually given after surgery where all detectable disease has been removed, but where there remains a statistical risk of relapse due to the presence of undetected disease. If known disease is left behind following surgery, then further treatment is not technically adjuvant.
A chemotherapy regimen is a regimen for chemotherapy, defining the drugs to be used, their dosage, the frequency and duration of treatments, and other considerations. In modern oncology, many regimens combine several chemotherapy drugs in combination chemotherapy. The majority of drugs used in cancer chemotherapy are cytostatic, many via cytotoxicity.
Stanford V, is a chemotherapy regimen intended as a first-line treatment for Hodgkin lymphoma. The regimen was developed in 1988, with the objective of maintaining a high remission rate while reducing the incidence of acute and long term toxicity, pulmonary damage, and sterility observed in alternative treatment regimens such as ABVD. The chemical agents used are:
BEACOPP is a chemotherapy regimen for treatment of Hodgkin lymphoma developed by the German Hodgkin Study Group used for patients in Stages > II or early with unfavorable risk factors. Patients typically receive treatment in cycles of 21 days with no drugs given on days 15–21. There also exists a more intensive regimen with cycles of 14 days. Usually a course of BEACOPP therapy consists of four, sometimes six to eight cycles, or in combination with ABVD. In some countries BEACOPP still is experimental, in others it is a standard therapy. In the United States, ABVD is generally given instead, because BEACOPP is perceived by practicing oncologists to have the potential to induce more secondary neoplasias. However, the final results from the GHSG HD14 trial indicate that "there were no overall differences in treatment-related mortality or secondary malignancies" of BEACOPP relative to ABVD.
Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is a slow-growing CD20 positive form of Hodgkin lymphoma, a cancer of the immune system's B cells.
Brentuximab vedotin, sold under the brand name Adcetris, is an antibody-drug conjugate medication used to treat relapsed or refractory Hodgkin lymphoma (HL) and systemic anaplastic large cell lymphoma (ALCL), a type of T cell non-Hodgkin lymphoma. It selectively targets tumor cells expressing the CD30 antigen, a defining marker of Hodgkin lymphoma and ALCL. The drug is being jointly marketed by Millennium Pharmaceuticals outside the US and by Seagen in the US.
Chemotherapy-induced nausea and vomiting (CINV) is a common side-effect of many cancer treatments. Nausea and vomiting are two of the most feared cancer treatment-related side effects for cancer patients and their families. In 1983, Coates et al. found that patients receiving chemotherapy ranked nausea and vomiting as the first and second most severe side effects, respectively. Up to 20% of patients receiving highly emetogenic agents in this era postponed, or even refused, potentially curative treatments. Since the 1990s, several novel classes of antiemetics have been developed and commercialized, becoming a nearly universal standard in chemotherapy regimens, and helping to better manage these symptoms in a large portion of patients. Efficient mediation of these unpleasant and sometimes debilitating symptoms results in increased quality of life for the patient, and better overall health of the patient, and, due to better patient tolerance, more effective treatment cycles.
High-dose chemotherapy and bone marrow transplant (HDC/BMT), also high-dose chemotherapy with autologous bone marrow transplant, was an ineffective treatment regimen for metastatic breast cancer, and later high-risk breast cancer, that was considered promising during the 1980s and 1990s. With an overall idea that more is better, this process involved taking cells from the person's bone marrow to store in a lab, then to give such high doses of chemotherapy drugs that the remaining bone marrow was destroyed, and then to inject the cells taken earlier back into the body as replacement. It was ultimately determined to be no more effective than normal treatment, and to have significantly higher side effects, including treatment-related death.
