OPINION
This is а medical malpractice case. Ap-pellee, Estle King, brought suit against Dr. James Bauer and Victoria Radiological Associates, claiming negligence on Bauer’s part in administering radiation therapy to her after surgery was performed to remove the lower left lobe of her lung. Trial was to a jury which found appellant negligent and awarded Mrs. King damages. The trial court entered judgment for King, plus prejudgment interest at a rate of six percent and post-judgment interest at the legal rate. Dr. Bauer appeals this judgment.
Appellant asserts five points of error on aрpeal. First, he claims that the trial court erred in awarding prejudgment interest from April 6,1978 to May 23,1983. Prejudgment interest is that interest calculated on a sum payable from the time of a loss or injury to the time of judgment. Republic National Bank of Dallas v. Northwest National Bank of Fort Worth,
Prejudgment interest is recoverable as a matter of right where an ascеrtainable sum of money is determined to have been due and payable at a date certain prior to judgment. Republican Nat’l Bank of Dallas v. Northwest National Bank of Fort Worth,
In appellants’ second and third points of error, they allege that the trial court erred in overruling their motion for judgment Non Obstante Veredicto and entering judgment for appellee because there was no evidence or, alternatively, insufficient evidence upon which the jury could find that the doctor was negligent in the treatment of Mrs. King.
In considering a “no evidence” or “insufficient evidence” point of еrror, we will follow the well established test set forth in Glover v. Texas General Indemnity Company,
In 1978, appellee was hospitalized, and the lower left lobe of her lung was removed. Dr. Dee Williams diagnosed her condition as cancer and determined that one of thirty lymph nodes which were removed at the time of her lung surgery was also found to be malignant. Thereafter, appellee underwent radiation therapy as a precautionary measure to ensure that no microscopic cancer cells remained in her body. This therapy was administered under the direction of Dr. Bauer, the appellant herein. Appellee later developed radiation myelopathy and complete paralysis of her lower body. She contends that the paralysis was proximately caused by the negligent treatment she received from Dr. Bauer. Radiation myelopathy is the degeneration of the spinal column secondary to the effects of exposure to radiation.
The record shows that Mrs. King began radiation treatments on February 27, 1978. She was involved in a “split course” treatment. This type of treatmеnt involves the patient receiving radiation treatment each day for a number of days, followed by a rest period of a certain number of days, and then the resumption of treatments for another period of time. Dr. Bauer testified that Mrs. King suffered from “broncho-alveolar” carcinoma, which he described as an unusual sub-type of lung cancer. The radiation treatment he prescribed was designed to kill any residual cancer cells. For her first treatment, she received 250 RADS.
The burden of proof in a medical malpractice case is on the patiеnt to prove that the physician has undertaken a mode or form of treatment which a reasonable and prudent member of the medical profession would not have taken under the same or similar circumstances. Hood v. Phillips,
An expert witness in a medical malpractice case should first state what the standаrd of care for a specific treatment is and then state the facts which show what the defendant doctor did. See Coan v. Winters,
Here, appellee introduced the deposition testimony of Dr. Joe Rector, Director of Radiation Therapy at St. Luke’s Hospital in Kansas City, Missouri. He testified that he had never examined the appellee, Mrs. King, but had read the records concerning her case. Dr. Rector claimed that development of radiation myelopathy was not a common consequence of radiation therapy following surgery. He said that the development of this condition depended upon the field size and dosage and a number of other things. Dr. Rector indicated that he normally did not notify his patients of the risk of “cord problems” unless, in an unusual сircumstance, a very large field size was utilized.
Dr. Hubert Rodney Withеrs, a physician specializing in radiation oncology, also testified by deposition. He testified that Mrs. King was treated in a fairly standard fashion, receiving a dose of about 4,500 RADS, with a boost dose of about one thousand RADS. He said that the total amount of radiation that the spinal cord can sаfely receive is between 4,500 and 5,000 RADS. Dr. Withers indicated that the effectiveness of the total dose depends on the size of the dose per fraction in which it is delivered. He said the common dose per fraction is about 200 RADS. It was Withers’ opinion that Mrs. King’s radiation mye-lopathy was caused by the lаrger doses she received in each fraction. According to
Dr. Vincent Collins, a medical doctor specializing in radiotherapy, also testified. Dr. Collins testified that the “intermediate person” will carry “his radiation dosage as far as he thinks he can.” He claimed that, if a doctor does not go far enough to kill the cancer, there is not much point in performing the treatment. He indicated that he believed the regime followed by Dr. Bauer was in accordance with the general standard. He further testified that he believed Dr. Bauer took the additional precaution to adjust one treatment method in the final few treatments to spare thе spinal cord, by directing the beam in another fashion. Dr. Collins said that, for individuals without problems, the 200 RADS per day treatment is acceptable. But often, for the patient’s convenience or for one reason or another, the schedule may be altered. He further testified that 300 RADS per day wоuld increase the risk of injury to the spinal cord if carried out without interruption. Mrs. King’s treatment, however, was interrupted. He also disagreed with Dr. Rector’s testimony that a field of 10 by 12 centimeters was considered a large field. Collins agreed that there is a relationship between the development of symptoms of myelopathy to total dose, time and number of fractions in which the radiation is given.
The burden of proof was upon Mrs. King to establish that Dr. Bauer undertook a mode or form of treatment which a reasonable and prudent member of the medical profession would not have undertaken under the same or similar circumstances. There is evidence, through the testimony of Dr. Rector and Dr. Withers, that the common dose per fraction is “about 200 RADS.” Dr. Rector testified that, as a rule of thumb in regard to the administration of radiation therapy, the standard was 1,000 RADS per week with five treatments per week at 200 RADS per treatment. Most of Mrs. King’s treatments constituted 300 RADS each.
Through the testimony of Doctors Rector and Withers, appellee did establish a general standard that physicians in the field of radiology use in determining the proper dosage that a patient is to receive when undеrgoing radiation therapy. We believe that she met her burden of showing a standard of care utilized by radiologists in treating their patients.
However, after considering all of the testimony of the medical experts, we find that there was no evidence for the jury to have found that Dr. Bauer fell below thаt standard. All of the medical experts agreed that 200 RADS per dose was a common manner to fractionate when treating a patient with radiation. On the other hand, there was no testimony that 300 RAD dosages, as such, fell below or violated the standard of care. In fact, Dr. Withers testified that a сommon dose of radiation would be to administer 3,000 RADS in ten fractions of 300 RADS each. While there was evidence that increased dosages per fraction increased the risk of myelopathy to a degree, there is no evidence that a 300 RAD fractioning that Mrs. King received was either an unaccepted mode of treatment or a form of treatment which was not supported by medical evidence. At most, Mrs. King produced some evidence through Dr. Rector’s testimony to the effect that he personally would not have given Mrs. King
In points of error four and five, appellants assert that the trial court erred in overruling defendant’s motion for judgment Non Obstante Veredicto because there was no evidence, or alternativеly, insufficient evidence upon which the jury could find that Dr. Bauer’s treatment was a proximate cause of Mrs. King’s injuries. Again, we will review all of the evidence according to the standard set forth herein above.
To establish proximate cause, the injury suffered must be a natural and probable result оf the act or omission complained of. State Highway Department v. Hinson,
All the medical professionals agreed that Mrs. King was suffering from myelopathy, which was caused by the radiation therapy. These points of error on causation are overruled.
The judgment of the trial court is reversed, and judgment is here rendered that plaintiff appellee take nothing.
Notes
. The units of measurement used to determine the amount of radiation one receives are known by the profession as RADS.
. Field size is the area the radiation beam is treating or affecting. The term "port" also means field size.
