Cancer Types Cancer types are categorized based on the functions/locations of the cells from which they originate: Carcinoma: a tumor derived from epithelial cells, those cells that line the inner or outer surfaces of our skin and organs (80-90% of all cancer cases reported) Sarcoma: a tumor derived from muscle, bone, cartilage, fat or connective tissues. Leukemia: a cancer derived from white blood cells or their precursors. Lymphoma: a cancer of bone marrow derived cells that affects the lymphatic system. Myelomas: a cancer involving the white blood cells responsible for the production of antibodies (B lymphocytes).

  • Chlormethine Hydrochloride (Brand Name: Ledaga®)
    www.scottishmedicines.org.uk Decision Explained Medicine: chlormethine hydrochloride (brand name: Ledaga®) Recordati Rare Diseases UK Ltd The Scottish Medicines Consortium (SMC) has assessed chlormethine hydrochloride for the topical treatment (treatment that is applied on the skin) of adults with mycosis fungoides cutaneous T-cell Pharmalymphoma Company (MF-CTCL). This document summarises the SMC decision and what it means for patients. What has SMC said? After careful consideration, SMC has accepted chlormethine hydrochloride for the treatment of MF- CTCL as described above. This SMC advice takes into account a confidential discount offered by the pharmaceutical company that improves the cost-effectiveness of chlormethine hydrochloride. In addition, SMC was able to apply a more flexible approach* in the assessment, as it is for a rare condition. What does SMC’s decision mean for patients? If your healthcare professional thinks that chlormethine hydrochloride for use as described above is the right medicine for you, you should be able to have the treatment on the NHS in Scotland. What is chlormethine hydrochloride used for? Chlormethine hydrochloride is used to treat MF-CTCL. MF-CTCL is a type of cancer where the T-cells (cells of the body’s immune system) in the skin grow in an uncontrolled way. This leads to a build-up of abnormal T-cells, which can cause oval or ring-like patches and plaques to form on the skin. These can cause pain and itching, which may be severe. MF-CTCL develops over a long period of time. It is the most common form of a group of cancers known as CTCLs, which are long-term cancers of cells in the immune system that affect the skin.

  • Other Alkylating Agents
    Anticancer agents The Alkylating agents The alkylating agents are the oldest group of cytostatic drugs. The first of them – mechlorethamine was introduced into therapy in 1949. The alkylating agents can contain one or two alkylating groups. In the body the alkylating agents may react with DNA, RNA and proteins, although their reaction with DNA is believed to be the most important. 1 • The primary target of DNA coross-linking agents is the actively dividing DNA molecule. • The DNA cross-linkers are all extremly reactive nucleophilic structures (+). • When encountered, the nucleophilic groups on various DNA bases (particularly, but not exclusively, the N7 of guaninę) readily attack the electrophilic drud, resulting in irreversible alkylation or complexation of the DNA base. • Some DNA alkylating agents, such as the nitrogen mustards and nitrosoureas, are bifunctional, meaning that one molecule of the drug can bind two distinct DNA bases. 2 • Most commonly, the alkylated bases are on different DNA molecules, and intrastrand DNA cross-linking through two guaninę N7 atoms results. • The DNA alkylating antineoplastics are not cel cycle specific, but they are more toxic to cells in the late G1 or S phases of the cycle. • This is a time when DNA unwinding and exposing its nucleotides, increasing the Chance that vulnerable DNA functional groups will encounter the nucleophilic antineoplastic drug and launch the nucleophilic attack that leads to its own destruction. • The DNA alkylators have a great capacity for inducing toth mutagenesis and carcinogenesis, they can promote caner in addition to treating it. 3 • Organometallic antineoplastics – Platinum coordination complexes, also cross-link DNA, and many do so by binding to adjacent guanine nucleotides, called disguanosine dinucleotides, on the single strand of DNA.

    Appendix B NATIONAL INSTITUTE FOR HEALTH AND CARE EXCELLENCE Health Technology Appraisal Chlormethine gel for treating mycosis fungoides-type cutaneous T-cell lymphoma [ID1589] Final scope Draft remit/appraisal objective To appraise the clinical and cost effectiveness of chlormethine gel within its marketing authorisation for treating mycosis fungoides-type cutaneous T-cell lymphoma. Background Lymphomas are cancers of the lymphatic system. They are broadly divided into Hodgkin’s and non-Hodgkin’s lymphomas. Cutaneous T-cell lymphoma is a rare type of non-Hodgkin’s lymphoma that affects the skin. It is caused by the uncontrolled growth of T-lymphocytes within the skin. Many types of cutaneous T-cell lymphoma start as flat, scaly, oval patches or plaques on the skin, which progress to skin tumours, and are often itchy and sometimes painful. Some people with cutaneous T-cell lymphoma experience swelling of the lymph nodes. Within the group of cutaneous T-cell lymphoma, there are distinct subtypes. Mycosis fungoides is the most common type of cutaneous T-cell lymphoma. It is usually a very slow-growing type of lymphoma that often only affects the skin and can stay under control for many years. In England in 2017, there were around 12,065 new cases of non-Hodgkin’s lymphomas and 796 people had a primary diagnosis of peripheral or cutaneous T-cell lymphoma1 There were 107 men and 72 women diagnosed with mycosis fungoides cutaneous T-cell lymphoma, in England in 2017.1 Median survival with early-stage disease, stage IA, IB and IIA, is reported as 35.5, 21.5 and 15.8 years, respectively.
