Overview
Cervical cancer was first described in 400 BC. In 1928, the Papanicolaou technique was developed by Papanicolaou to diagnose cervical cancer. In 1976, Harald zur Hausen and Gisam were the first to discover the association between HPV and development of cervical cancer.
Historical Perspective
- 1841- Rigoni found that cervical cancer was rare in nun's, except for those who had been sexually active before entering the convent.
- Epidemiologists working in the early 20th century noted that cervical cancer behaved like a sexually transmitted disease.
- Cervical cancer was noted to be common in female sex worker's.
- It was more common in the second wives of men whose first wives had died from cervical cancer.
- It was rare in Jewish women.[1]
- 1925 - Hans Hinselmann|Hinselmann invented the colposcope
- 1928 - Papanicolaou developed the Papanicolaou technique
- 1935 - Syverton and Berry discovered a relationship between RPV (Rabbit Papillomavirus) and skin cancer in rabbit's. (HPV is species-specific and therefore cannot be transmitted to rabbits)
- 1941 - Papanicolaou and Trout: Pap smear screening began
- 1946 - Aylesbury spatula was developed to scrape the cervix, collecting the sample for the Pap smear
- 1940s- 1950s- The historical observations suggested that cervical cancer could be caused by a sexually transmitted agent. Initial research in the 1940s and 1950s attributed cervical cancer to smegma[2]
- 1949 - A description of human papillomavirus (HPV) by electron microscopy
- 1951 - First successful in-vitro cell line, HeLa, derived from biopsy of cervical cancer of Henrietta Lacks
- 1963- HPV-DNA was identified
- 1976 - Harald zur Hausen and Gisam found HPV DNA in cervical cancer and genital warts; Hausen later won the Nobel Prize for his work[3]
- 1960-1970- During the 1960s and 1970s it was suspected that infection with herpes simplex virus was the cause of the disease. In summary, HSV was seen as a likely cause because it is known to survive in the female reproductive tract, to be transmitted sexually in a way compatible with known risk factors, such as promiscuity and low socioeconomic status.[4] Herpes viruses were also implicated in other malignant diseases, including Burkitt's lymphoma, Nasopharyngeal carcinoma, Marek's disease and the Lucké renal adenocarcinoma. HSV was recovered from cervical tumour cells.It has since been demonstrated that HPV is implicated in virtually all cervical cancers.[5] Specific viral subtypes implicated are HPV 16, 18, 31, 45 and others.
- 1980- In work that was initiated in the mid 1980s, the HPV vaccine was developed, in parallel, by researchers at Georgetown University Medical Center, the University of Rochester, the University of Queensland in Australia, and the U.S. National Cancer Institute.[6]
- 1988 - Bethesda System for reporting Pap results was developed
- 1995 - In the United States, physicians who fail to diagnose cervical cancer from a pap smear have been convicted of negligent homicide. In 1988 and 1989, Karen Smith had received pap smears which were argued to have "unequivocally" shown that she had cancer; yet the lab had not made the diagnosis. She died on March 8 1995. Later, a physician and a laboratory technician were convicted of negligent homicide. These events have led to even more rigorous quality assurance programs, and to emphasizing that this is a screening, not a diagnostic, test, associated with a small irreducible error rate.
- Mid-1990- Since the mid-1990s,the Sure-Path (TriPath Imaging) and Thin-Prep (Cytyc Corp) techniques were used,they are based around placing the sample into a vial containing a liquid medium which preserves the cells.
- 2006 - First HPV vaccine FDA was approved,under the trade name Gardasil.
- 2007 - In the Canadian provinces of Ontario, Prince Edward Island, Newfoundland and Nova Scotia, free vaccinations to protect women against HPV are slated to begin in September 2007 and will be offered to girls 11-14 in age. Similar vaccination programs are also being planned in British Columbia and Quebec.[7][8][9]Australia has decided to fund the HPV vaccine under the National Immunisation Program commencing in the 2007 school year.[10] In the U.K. a similar free vaccination program is being considered,[11] while in the United States, many states are preparing bills to handle issuing the HPV vaccine.
- 2014- In April 2014, the U.S. Food and Drug Administration approved an HPV DNA test that can be used alone for the primary screening of cervical cancer risk in women aged 25 years and older.
