Perspective
Fourth pillar of cancer treatment is about to make a breakthrough
A series of new studies about regional hyperthermia of certain tumors show amazing results: Patients undergoing so-called "hyperthermia" treatment have a one to three times higher five-year survival rate than with standard therapy. Scientists in Berlin have been able for the first time to combine the use of hyperthermia with magnetic resonance imaging. As a result, one of the greatest technical problems has been resolved- it is now possible to control heat during treatment.
The number of cancer patients in Europe has increased in the last three years from 2.9 to 3.2 million. The latest numbers from 25 Member States determined by the International Cancer Research Center IARC in Lyon shows that in 2007 alone 1.7 million Europeans died from cancer. As a general rule, only 5 out of 10 men and 6 out of 10 women are still alive five years after the beginning of tumor therapy among 8 relevant types of tumors.

Fallopian tubes: Is pregnancy possible with only one?
Mayo Clinic breast-health specialist Sandhya Pruthi, M.D.:
Pregnancy is possible with only one fallopian tube — as long as you have one or both ovaries, you still ovulate, and the remaining fallopian tube is healthy.
Normally, a single egg is released each month by one of the ovaries. The egg travels to one of the fallopian tubes — typically the adjacent tube — where a sperm may fertilize it. The fertilized egg then travels to the uterus.
Ovulation tends to alternate between the ovaries. If you have only one fallopian tube, you're most likely to conceive on a month in which the egg is released from the ovary nearest your fallopian tube. Although it may be possible for an egg released from one ovary to travel to the fallopian tube on the opposite side, this is rare. Instead, any eggs released from the ovary on the opposite side typically won't have a chance to be fertilized. The egg will simply break down, and you'll have your next period as usual.

Definition of Fallopian Tube
Fallopian tube: One of the two Fallopian tubes that transport the egg from the ovary to the uterus (the womb). In the diagram, the Fallopian tubes are not labeled but are well shown running between the uterus and ovaries. The Fallopian tubes have small hair-like projections called cilia on the cells of the lining. These tubal cilia are essential to the movement of the egg through the tube into the uterus. If the tubal cilia are damaged by infection, the egg may not get 'pushed along' normally but may stay in the tube. Infection can also cause partial or complete blockage of the tube with scar tissue, physically preventing the egg from getting to the uterus.

Fallopian Tube Cancer
Fallopian tube cancer is usually adenocarcinoma, manifesting as an adnexal mass or as vague symptoms. Diagnosis, staging, and treatment are surgical. Primary fallopian tube cancer is rare. Average age at diagnosis is 50 to 60. Risk factors include chronic salpingitis, other inflammatory disorders (eg, TB), and infertility. Most (> 95%) fallopian tube cancers are papillary serous adenocarcinomas; a few are sarcomas. Spread, like that of ovarian cancer, is by direct extension, by peritoneal seeding, or through the lymphatics. Most patients present with an adnexal mass or vague abdominal or pelvic symptoms (eg, abdominal discomfort, bloating, pain). A few patients present with hydrops tubae profluens (a triad of pelvic pain, copious watery discharge, and adnexal mass), which is more specific. Imaging is typically done with CT scan. A distended solid adnexal mass and normal ovaries suggest fallopian tube cancer.

Cannabis Chemical Pregnancy Link
A cannabis-like chemical may be important for normal pregnancy, US researchers believe. Reactions to cannabinoid chemicals were important for the embryo to move along the fallopian tube towards the womb, animal experiments showed. The Vanderbilt University scientists told Nature Medicine their findings could be important for understanding why ectopic pregnancies can occur. This is when the embryo starts to grow outside the womb.
The researchers recommended more research to find out whether cannabis use might increase the risk of ectopic pregnancies. In normal pregnancy, eggs make their way from the ovaries to the womb through the fallopian tubes, where they may be fertilised by a sperm. The fertilised egg continues on to the womb, where it implants itself to the wall and continues to grow.

Fallopian Tube Procedures for Infertility
A fallopian tube blockage typically prevents successful passage of the egg to the sperm, or the fertilized egg to the uterus. Surgery can be used to try to correct this common cause of infertility. The specific type of surgery depends on the location and extent of the fallopian tube blockage. ome tubal procedures can be done using microsurgical techniques, either during open abdominal surgery or using laparoscopy through a small incision. The surgeon must have special training and expertise in microsurgery techniques and/or laparoscopy. This general overview describes the most common tubal procedures.
Tubal reanastomosis typically is used to reverse a tubal ligation or to repair a portion of the fallopian tube damaged by disease. The blocked or diseased portion of the tube is removed, and the two healthy ends of the tube are then joined. This procedure usually is done through an abdominal incision (laparotomy).

Problems with the Fallopian Tubes
The fallopian tubes may be abnormal in structure or function. If they are blocked, the egg cannot move from the ovary to the uterus. Causes of fallopian tube problems include previous infections (such as pelvic inflammatory disease), endometriosis, a ruptured appendix, and surgery in the pelvis. A mislocated (ectopic) pregnancy in the fallopian tubes can also cause damage. Structural disorders can block the fallopian tubes. These disorders include birth defects of the uterus and fallopian tubes, fibroids in the uterus, and bands of scar tissue between normally unconnected structures (adhesions) in the uterus or pelvis. To determine whether the fallopian tubes are blocked, doctors can use hysterosalpingography. In this procedure, x-rays are taken after a radiopaque dye is injected through the cervix. The dye outlines the interior of the uterus and fallopian tubes.
