Cells b e c o m e cancerous because they do not get the right messages cheap zofran 4 mg with mastercard, either because of a deficiency in the D N A transcription process or because of a failure in execution of the instructions order 8 mg zofran. This finding opens up a whole n e w approach to the care of patients with metastatic thyroid carcinoma cheap zofran 8mg on-line, s o m e of w h o m m a y have an increase in serum thyroglobulin with no other indication of where the métastasés are located. Hippocrates wrote: “It is disgraceful in every art and m o r e especially in medicine, after m u c h trouble, m u c h display and m u c h talk, to do no goo d after all. C O S T E F F E C T I V E N E S S O n e m a y ask w h o is going to pay for all these expensive studies in this era of cost containment? O n e might also think that there could not have been a worse time to introduce a new, expensive, high-tech procedure into medical practice. Paradoxi­ cally, nothing could be m o r e helpful than studies of cost effectiveness in increasing the use of nuclear medicine procedures. While there is clearly an overcapacity in m u c h of the supply of medical care, there is undercapacity and underutilization of nuclear medicine capacity, which is w h y it has been called the ‘best kept secret in medicine’. For example, one can exchange the cost of the nuclear medicine studies for surgery costs, which are far greater. Operative complications can be reduced by increasing knowledge of the extent of the spread of cancer. O n e can n o w be certain that w h e n the patient is operated upon, he or she will not be found to have lesions that m a k e the surgery fruitless. O v e r 30 0 0 0 thoracotomies are performed where the patients are found to have inoperable lung cancer. Every year, 25 0 0 0 thoracotomies are performed in the U S A for solitary pulmonary nodules that prove to be benign. There w a s a change in stage in 2 6 % of the patients (19/71), s o m e patients going to a higher and s o m e to a lower stage. T h oracotomy w a s avoided in 1 5 % of patients (16/104) with non-small-cell lung cancer. T h e sensitivity w a s 9 4 % , w hich w a s sufficiently high to avoid surgery, w h e n c o m bined with other data such as the appearance of the lesion in the radiograph, and the clinical history and physical examination of the patient. In 15 of 52 patients, they found one or m o r e foci of abnormal 18F D G accumulation beyond the lungs and mediastinal structures. Lasagna wrote: “Often w e d o n ’t k n o w h o w to tailor specific drugs to specific patients very well; w e could do that better and m a k e a qua n t u m j u m p in efficacy without even c o m i n g u p with any n e w drugs. For example, at Johns Hopkins w h e n patients are to have a partial hepatectomy for cancer metastatic to the liver, 25 % are found at surgery to be inoperable for one of the following reasons: (1) Both lobes of the liver w ere involved; (2) l y m p h nodes were involved; or (3) there were peritoneal or other extrahepatic métastasés. Others reported on the cost effectiveness of l8F D G imaging in recurrent colorectal cancer. T h e imaging studies resulted in major changes in the patient’s care in 4 0 % of the patients; surgery w a s avoided in 2 0 patients, the type of surgery changed in 2. Partial hepatectomy w a s avoided in 12 patients, laparotomy in 6 and thoracotomy in 2. O n e of the advantages of radiotracer studies in patients with cancer is that whole body imaging can be routine. For example, in 31 patients with elevated tumour markers, including carcinoembryonic antigen ( C E A ) and СA 125, 5 3 % of lesions were detected b y 18F D G studies [8]. A b o u t 5 0 0 0 w o m e n are operated upon every year in the U S A for a ‘second look’to see if they have residual ovarian cancer. H u b n e r [9] examined such patients with ovarian cancer to find out whether they had metastatic disease. There were three false negatives, a performance better than C T or magnetic resonance imaging ( M R I ) results in the s a m e patients. If this had been k n o w n prior to surgery, the operation wo u l d have been avoided and the patients started on hormonal or chemotherapy. It m a y then take a mo n t h or m o r e to determine whether the chemotherapy has been effective. B R E A S T C A N C E R Tiling [10] observed that 8 3 % of 58 patients w h o had a m a m m o g r a p h y were suggestive of cancer of the breast. Particularly in patients with dense breasts, one can often supplement the information from m a m m o g r a p h y with the M I B I study [11]. Thus, one should refer to ‘increased 18F D G accumulation’rather than ‘increased glucose utilization’w h e n referring to l8F D G uptake in tumours. T h e l u m p constant reflects the difference in the rate of phosphorylation between deoxyglucose and glucose. A n l8F D G para­ metric image, then, reflects the product of the l u m p constant and the metabolic rate for glucose. T h e increased l u m p constant reflects increased activity of hexokinase enz y m e s 2 and 3, which are associated with anaerobic glycolysis. A X I L L A R Y N O D E I N V O L V E M E N T I N B R E A S T C A N C E R T h e question often arises about whether surgical exploration of the axilla should be carried out to search for involved l y m p h nodes. T h e important decision is whether the patient should have adjuvant chemotherapy, or m o r e intensive chemotherapy, if nodes are k n o w n to be involved. W h e n the patient w a s found to have macro- axillary métastasés, axillary exploration is not needed because the patient can be started on intensive chemotherapy.

In another scenario buy 4mg zofran with visa, radiation can cause two breaks in one arm of a chromosome buy zofran 4mg free shipping, resulting in three fragments order zofran 4 mg free shipping, only two of which combine with the loss of the third. Trans- location and deletion, although not as harmful to the cell, cause late effects such as carcinogenesis and hereditary effects due to mismatch or loss of genetic material. An alternative to deletion is the combination of all three fragments into a chromosome with changes along the broken line as shown in Figure 15. This process is called inversion, which has all the original genetic material except a change in the sequence of genes and hence is not as detrimental to the cell. Chromosome aberrations by double-strand breaks occur more frequently at high-dose rates than at low- dose rates because of less time to repair and fewer chances of combining Dicentric Acentric Translocation A B Fig. Combination of these four fragments leads to dicentric and acentric chromosomes (A) or translocation (B). For example, a-particles, protons, and neu- trons will cause more chromosome aberrations than g-rays. Damaged cells that survive may later induce carcinogenesis or other abnormalities. A variety of reactions that can occur after radiation interacts with water molecules is shown below. The number of free radicals produced by ionizing radiation depends on the total dose but not on the dose rate. It has been found that the majority of radiation-induced damage results from the indirect action mechanism be- cause water constitutes nearly 70% of the composition of the cell. Radiosensitivity of Cells In living matter, there are two types of cells: differentiated and undifferen- tiated. Undifferentiated cells do not have any specific physiologic function except to develop into mature cells. In contrast, all mature cells are differentiated and perform specific functions in the living body. According to the law of Bergonié and Tribondeau, undifferentiated cells that are undergoing active mitosis are most sensitive to radiation, and dif- ferentiated or mature cells are least affected by radiation. For differentiated cells, it means loss of cellular function, whereas for undifferentiated cells it means loss of reproductivity. As can be seen, lymphocytes, though mature cells, are most sensitive to radi- ation, owing to a large nucleus; nuclear material is more radiosensitive. Nerve cells and muscle cells are totally differentiated cells and therefore 238 15. The tissue or organ that contains more radiosensitive cells will be highly radiosensitive and vice versa. For example, bone marrow containing radiosensitive erythroblasts is very radiosensitive, whereas nerves and muscles containing radioresistant cells are less radiosensitive. Cell Survival Curves When mammalian cells are irradiated, not all cells are affected to the same extent. The cellular response to radiation is illustrated by what is called the cell survival curve. It is obtained by plotting the dose along the linear X-axis and the surviving fraction along the logarithmic Y-axis. Surviving cells are those cells that retain all reproductive as well as func- tional activities after irradiation, whereas the death of cells is indicated by the loss of their function in differentiated cells and by the loss of repro- Cell Survival Curves 239 ductive activity in undifferentiated cells. It should be noted that thousands of grays are needed to kill differentiated cells, whereas only hundreds of grays are needed for undifferentiated cells. This straight line portion on the semilog plot is an exponential curve on a linear plot. This curve based on a multitarget model is characterized by three parameters: D0 (dose at which 37% of cells survive), the extrapolation number n, and the quasithreshold dose Dq, and they are related by the expression logen = Dq/D0 (15. After Dq, the plot becomes linear on a semilog scale, indicating an exponential dose–response relationship. The extrapolation number n is obtained by extrapolating the linear portion of the curve back to the ordinate. D0 is the dose obtained from the slope of the linear portion of the curve, at which 37% of the cells survive. Radiation Biology after irradiation, and cell killing is minimal, which is due to very limited radiation damage to the cell. D0 is determined from the slope of the straight line portion of the sur- vival curve. For example, a large value of D0 for a type of cell means that the cells are less radiosensitive and vice versa. The extrapolation number n is obtained by extrapolating the straight line portion of the survival curve back to the Y-axis. Its value depends on the width of the shoulder of the survival curve, that is, the quasithreshold value, Dq.
